Subject [jira] [Commented] (AMBARI-3893) jobs submitted thorugh webhcat gets stuck at applicationmaster
Date Wed, 27 Nov 2013 21:18:35 GMT

    [ https://issues.apache.org/jira/browse/AMBARI-3893?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13834155#comment-13834155
] 

Dilli Arumugam commented on AMBARI-3893:
----------------------------------------

With help from Srimanth, changed the following configuration parameters using Ambari console.
After the changes,  wordcount job submitted  through webhcat succeeded.

Yarn:Scheduler
      yarn.scheduler.minimum-allocation-mb: 683 -> 300

MapReduece2: General
     Default virtual memory for a job's map-task: 341 -> 250
     Default virtual memory for a job's reduce-task: 683 -> 500

MapReduce2: Advanced:
    yarn.app.mapreduce.am.resource.mb: 683 -> 300

It appears we would need this configuration change only for single host cluster.
