kylin's Issues

Can't add extra columns to existing cube

When add new dimension into existing cube (have to be "disable" status before edit it), there's error message will popup when "save" the cube.
The root cause is the "rowkey" section of cube metadata mismatched with dimensions: each dimension should present in rowkey also.

tab at step Dimensions show unnormal when edit cube

when edit cube at step 'Dimensions '

If user switch between 'Join','Hierarchy','Derived'.

the style of tabcontent is not friendly.

Remote JDBC Driver

docs are missing

Document link in menu on web-site goes nowhere. I guess the docs will come later.

Group Hive tables in Project level

Currently, all Hive tables are system wild that mean all projects can access and build cube from any table. Also there are many confuse on the web interface and hard to isolate ACL.
To well organize and support future feature, here are the changes relative to Table and Project:

One table has to belong to at least one project (1:M)
One project could contains many tables, all this project cubes' backend tables have to be included in this project
Cube Modeler could sync Hive Table Metadata at project level
Different projects could contain different Hive Table's version (TBD)

Install script not work on Cloudera sandbox

Current install script works for HDP 2.1 Sandbox but not works for Cloudera sandbox.

Increase HDFS block size 1GB

Increase HDFS block size 1GB or close, use "mapred.max.split.size" to control mapper's input size. Verify mapreduce performance retains after the change.

MapReduce Job information can't display on sandbox deployment

MapReduce Job link in Cube Build Job will use "sandbox.hortonworks.com" as default hostname, this will failed to load exactly job information as below:

Replace "sandbox.hortonworks.com" with "127.0.0.1" will redirect to Job History page but still failed with same problem, replace again with "127.0.0.1" will show exactly information:

To fix this issue, add following content in your /etc/hosts file:

127.0.0.1 localhost sandbox.hortonworks.com

OAuth Support for user login

Support login with OAuth protocol

Add validation step of cube build job as first one

Add one job step: "Validation" to run series check to ensure cube build job will start without obvious issues:

Fact Table have to contains at least one records
No Duplicate rows in lookup tables
At least one records after Hive Join Step (especially to check "inner join" case)

Raise exception and stop entire cube build job with "Validation Failed" message.

Sort job list by last modified timestamp

The current jobs order on Job List page is not sorted by last modified timestamp which will hide the last jobs on the page. User have to filter by status or project to get the last job.

Merge metadata tables

There are too many HBase tables for metadata now. It will be great to merge them:

One for all metadata and instance, using different column family for metadata and instance.
One for job information, including cube build job and others which will coming soon like cardinality.

Some NPM error causes ERROR exit?

snapshot:

Support "Copy" on grid result

Currently, user can't copy data from grid result:

Automatically create local cluster for running tests

Phoenix automatically creates a mini-cluster when you run a test. For example, download the latest Phoenix, do 'mvn -DskipTests install', open UpsertBigValuesIT.java in Intellij, and press Control-Shift-F10. (It works in Eclipse too.) The test creates a mini-cluster, runs 4 test methods, and tears down the cluster. It takes 1 minute to run. No configuration whatsoever is required.

I know that this kind of automation hard to achieve, but it allows casual committers (like me) to get involved in the project without spending hours or days setting up the environment.

Since Phoenix and Kylin are both based on HBase, you could probably copy-paste their maven XML and the base classes for their tests.

Cube migration to check dup dict & snapshot

Add client information into Job

As an administer and cube owner, I would like to know one job be triggered by which user, when, and triggered by which client, corn tab, web, 3rd party client...

Clean code and open source on github.com

Release first version to github.com

Expose SQL explain plan in REST API

Expose SQL explain in REST API for client to consume

styles.css forces font HelveticaNeueLight, which does not display well.

Viewing the site in Chrome Version 37.0.2062.124 m (64-bit), MSIE 9.08 and FireFox 17.04 in Windows 7.

In /assets/css/styles.css, this section @ line 294

.main {
    position: relative;
    margin: 0;

    color: #666666;
    padding: 0;
}

Only a few characters are visible. By removing the font-family line under the .main definition, the browsers can select the proper replacement font.

Upgrade Calcite to 0.9.x

HBase schema enhancement

Since the data table only write once and won't be updated, set VERSION to 1
Shorten the column family name, e.g., from "Fn" to "n"
For the data tables, remove IN_MEMORY setting

Check duplicate rows in lookup table

When there are duplicate rows in lookup table, the cube build job will fail.
Add this check into "Validation" step of Cube Build Job:
#37

Also enable this single step available to be called from shell or rest, which will help cube modeler check such data quality before trigger cube build job.

Can't get cube segment size

I build test_kylin_cube_with_slr_empty failed, it shows that can't get cube segment size. The error log as followed:
#13 Step Name: Load HFile to HBase Table

Support multiple column distinct count

Make count distinct(A, B) work, currently calcite only support count distinct on one column.

Excute query failed and always show loading cubes

after install the kylin, the kylin.log file shows the exception:

Ambari plugin to manage Kylin service

Ambari is great tool to manage most of Hadoop components in one single place:

It make sense to use Ambari to easy manage Kylin serivce in same place.
Requirement:

Deploy and install Kylin service via Ambari
Start and Stop Kylin service through Ambari
Display Kylin service status on Ambari Web

[Call Volunteer!]

We are not Ambari expert, please let's know if you have interesting to contribute on this!

Enhance cuboid geneatation to have tail-zero only

Now we only support hierarchy aggregation group that will generate tail-zero & tail-one partial cuboid.

In many case, user may want independent cuboid that will only has tail-zero cuboid. It can greatly reduce the cube size.

Auto merge after incremental refresh on cube which contains "Distinct Count" measure

When cube contains "Distinct Count" measure, the query result will not correct without merge old cube segment and new one (with incremental refresh). And the current "Merge" operation will bring downtime for such cube to serve query (not available before merge finished).
To avoid such issue, enhance job engine to auto merge such segment after incremental build success, then swap new HTable with old one which will not impact queries too much (seconds).

There's should no default project

There's should no default project.

And, current test cube belongs to two projects which is not correct logical as design:

Install scripted finished in my virtual machine, but cannot visit via http://localhost:9080

Use DoubleDouble to replace BigDecimal in both Build Engine and Query Engine

It seems DoubleDouble is faster than BigDecimal

Remove MR Job relative link for none-MapReduce Job step

Remove MR job relative links from none-Map Reduce Job steps. The MR Job link already removed but there's still others like Eagle Link

Display job status with exactly percentage number

The current MR job step can't show exactly percentage number about the progress as below

Job job_1415330509679_11957 get status check result.
2014-11-07 20:28:59.654 - State of Hadoop job: job_1415330509679_11957:RUNNING - UNDEFINED

Fetch exactly progress with exactly number and display in Cube Build Job steps

BarChart and PieChart not work correctly on Kylin query result page

When switch to BarChart and PieChart, the graphic shows not correct.

Display Duration with current timestamp

The current "Duration" will only show exactly number after the step finished.
Display Duration with current timestamp for well monitor:
Duration = Current Timestamp - Start Timestamp

Only cache ScanOutOfLimitException exception

Derive meaningful cost in OLAP relational operator

Currently the sub-classes of OLAPRel implement computeSelfCost() in a native way, which is multiply super.computeSelfCost() by a 0.05 such that OLAP cost is very small and is always favored by optimization engine.

The cost shall be derived in more meaningful way to be comparable with Calcite cost.

Cube's last modified time will set to wrong date when incremental job failed

When incremental refresh job failed, the cube's last modified time will set to 1970-01-01 08:00:00
This is wrong value, it should always keep the last success refresh timestamp.

Screenshot:

collect metrics from log and show on GUI

Merge "Build" and "Refresh" in one button

There are two button for cube build:

Build: build cube from beginning and incremental load. User could specify start and end date.
Refresh: re-build cube with current date range

Using one button to simplify and reduce confuse for users to build cube:

Use "Build Cube" as menu
Popup dialog for user to specify start (if appliable) and end date,
Fulfill that values from existing cube metadata and instance

Kylin Shell Client

Support connect and execute SQL with Kylin from Shell Client

Remove hardcode hostname

The current deployment script using hardcode for the hostname. it could fail deployment on Hadoop cluster other than sandbox from Hortonworks and Cloudera.

Can't get master address from ZooKeeper when installing Kylin on Hortonworks Sandbox
