cesnet-hadoop's Issues

java.lang.IllegalStateException: Variable substitution depth too large: 20

Hello!
I have 36 data dirs on the one server.
Then I start data node I get this error:

2018-06-22 15:11:47,015 INFO org.apache.hadoop.hdfs.server.datanode.DataNode: registered UNIX signal handlers for [TERM, HUP, INT]

For fix this error I replaced ${user.name} with actual hdfs username.
For now, I just created variable

class hadoop::params {

  $hadoop_user_name = lookup('hadoop::params:hadoop_user_name', String, 'first', '${user.name}')

and use it in code:

  $hdfs_datanode_suffix = "${::osfamily}-${::operatingsystem}" ? {
    /RedHat-Fedora/ => "/$hadoop_user_name/dfs/datanode",
    /Debian|RedHat/ => "/$hadoop_user_name/dfs/data",
  }

But variable ${user.name} widely used and I don't know how to fix it in the right way.

mapreduce.jobhistory.webapps.address typo

Hi,

Thank you for this module.

Confirming with the docs: https://hadoop.apache.org/docs/r2.7.2/hadoop-mapreduce-client/hadoop-mapreduce-client-core/mapred-default.xml#mapreduce.jobhistory.webapp.address

It appears there is a typo in manifests/init.pp#217

- 'mapreduce.jobhistory.webapps.address' => "${hs_hostname}:19888",
+ 'mapreduce.jobhistory.webapp.address' => "${hs_hostname}:19888",

hdfs_port_namenode_http is incorrectly set if HDFS package are not installed using cesnet-hadoop

Hello,

Following snippet from manifests/init.pp is not working correcly for me and imho, is incorrect.

  case "${::hadoop::version}." {
    /^2(\.)?/: {
      $hdfs_port_namenode_http = '50070'
      $hdfs_port_namenode_https = '50470'
      $hdfs_port_namenode = '8020'
    }
    default: {
      $hdfs_port_namenode_http = '9870'
      $hdfs_port_namenode_https = '9871'
      # changed back from 9820 to 8020 in Hadoop 3.0.1
      $hdfs_port_namenode = '8020'
    }
  }

If HDFS has been deployed manually, without using the class itself ::hadoop:version is undefined and thus, defaults to hadoop 3.x port, which is, in my case, incorrect.

Would you at least provide a way to override these ports from class parameters ?

Best regards, Adam.

Failed to parse template hadoop/hadoop/core-site.xml.erb

Hello,
I try to run hadoop on a CentOS box and fail at the very beginning:

puppet agent -t

Info: Retrieving pluginfacts
Info: Retrieving plugin
Info: Loading facts
Info: Loading facts
Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Failed to parse template hadoop/hadoop/core-site.xml.erb:

Illegal fully qualified name with parser = future

Hello,

Latest version of the module seems to fail with future parser:

Error: Could not retrieve catalog from remote server: Error 400 on SERVER: Evaluation Error: Error while evaluating a Function Call, Illegal fully qualified name in file /etc/puppet/environments/production/modules/zookeeper/manifests/config.pp at line 60:38 at /etc/puppet/environments/production/modules/zookeeper/manifests/init.pp:52:3 on node hdfs-master1.service.earthlab.lu

The same occurs at line 67.

It seems that replacing with content => "${_myid}" fixes the issue (for me) but it may have broken something else.

Best regards, Adam.

Support for CDH 6

CDH 6 is released (https://archive.cloudera.com/cdh6/6.0.0/). Do you have plans to support it?
