Vagrant project to spin up a single node VM running current versions of Hadoop, Hive and Spark

Vagrant for Hadoop, Spark and Hive

Introduction

Vagrant project to spin up a single virtual machine running:

• Hadoop 2.7.3
• Hive 1.2.2
• Spark 2.1.1
• mysql 5.7 (for hive metastore)
• Tez 0.8.5
• Sqoop 1.4.6
• Pig 0.17.0
• flume 1.7.0
• Zeppelin 0.7.2 (with Spark/scala, md, file and JDBC interpreters)

The virtual machine will be running the following services:

• HDFS NameNode + DataNode
• YARN ResourceManager/NodeManager + JobHistoryServer + ProxyServer
• Hive metastore and server2
• Spark history server
• mysql
• zeppelin notebook server (not started by default - see below)

Getting Started

1. Download and install VirtualBox
2. Download and install Vagrant.
3. Go to releases and download and extract the latest source of this project.
4. In your terminal change your directory into the project directory (i.e. cd vagrant-hadoop-spark-hive-<version>).
5. Run vagrant up to create the VM (NOTE This will take a while the first time as many dependancies are downloaded - subsequent deployments will be quicker as dependancies are cached in the resources directory).
6. Execute vagrant ssh to login to the VM.

Map Reduce - Tez

By default map reduce jobs will be executed via Tez to change this to standard MR, change the following parameter in $HADOOP_CONF/mapred-site.xml from: -

    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn-tez</value>
    </property>

to

    <property>
        <name>mapreduce.framework.name</name>
        <value>yarn</value>
    </property>

Web user interfaces

Here are some useful links to navigate to various UI's:

• YARN resource manager: (http://10.211.55.101:8088)
• Job history: (http://10.211.55.101:19888/jobhistory/)
• HDFS: (http://10.211.55.101:50070/dfshealth.html)
• Spark history server: (http://10.211.55.101:18080)
• Spark context UI (if a Spark context is running): (http://10.211.55.101:4040)
• Zeppelin notebook (if notebook server is started) (http://10.211.55.101:8080)

Apache Zeppelin notebook server

Apache Zeppelin together with spark, md, file and JDBC interpreters is installed by default but not started. To manually start the zeppelin daemon run: -

vagrant ssh
zeppelin-daemon.sh start

as ubuntu user from the command line.

Notebook server can then be accessed via http://10.211.55.101:8080.

Mysql

mysql database connection

• [email protected]:3306 (for root DBA access - password is 'root')
• [email protected]:3306 (for hive metastore user - password is 'hive')

Shared Folder

Vagrant automatically mounts the folder containing the Vagrant file from the host machine into the guest machine as /vagrant inside the guest.

Validating your virtual machine setup

To test out the virtual machine setup, and for examples of how to run MapReduce, Hive and Spark, head on over to VALIDATING.md.

Managment of Vagrant VM

To stop the VM and preserve all setup/data within the VM: -

vagrant halt

or

vagrant suspend

Issue a vagrant up command again to restart the VM from where you left off.

To completely wipe the VM so that vagrant up command gives you a fresh machine: -

vagrant destroy

Then issue vagrant up command as usual.

To shutdown services cleanly

$ vagrant ssh
$ sudo -sE
$ /vagrant/scripts/stop-spark.sh
$ /vagrant/scripts/stop-hadoop.sh
$ systemctl stop mysql.service

Swapspace - Memory

Spark in particular needs quite a bit of memory to run - to work around this a swapspace daemon is also configured and started that uses normal disk to dynamically allocate swapspace when memory is low.

More advanced setup

If you'd like to learn more about working and optimizing Vagrant then take a look at ADVANCED.md.
