[jira] [Commented] (AMBARI-14679) When Spark is added later to a cluster with YARN deployed then yarn-site is not modified

    [ https://issues.apache.org/jira/browse/AMBARI-14679?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15102624#comment-15102624 ] 

Swapan Shridhar commented on AMBARI-14679:
------------------------------------------

Following fix has been done.
- Added the YARN property (yarn.nodemanager.aux-services, yarn.nodemanager.aux-services.spark_shuffle.class) dependency on property (spark.yarn.queue).
- Fixed the 2.4/stack_advisor code to add "spark_shuffle" value only if it doesnt exist in property "yarn.nodemanager.aux-services".

> If Spark is added to an existing cluster with YARN using HDP 2.4, then yarn-site:yarn.nodemanager.aux-services is not modified to include spark_shuffle.
> Recommendation show is :
> {code}
> Recommendations: {'yarn.timeline-service.entity-group-fs-store.group-id-plugin-classes': '', 'yarn.nodemanager.container-executor.class': 'org.apache.hadoop.yarn.server.nodemanager.DefaultContainerExecutor', 'yarn.nodemanager.aux-services.spark_shuffle.class': 'org.apache.spark.network.yarn.YarnShuffleService', 'yarn.scheduler.minimum-allocation-vcores': '1', 'yarn.scheduler.maximum-allocation-vcores': '1', 'yarn.nodemanager.resource.memory-mb': '1024', 'yarn.scheduler.minimum-allocation-mb': '341', 'yarn.nodemanager.resource.cpu-vcores': '1', 'yarn.nodemanager.aux-services': 'mapreduce_shuffle, 'yarn.scheduler.maximum-allocation-mb': '1024', 'yarn.nodemanager.linux-container-executor.group': 'hadoop'}
> {code}
> But with SPARK added, it should be :
> {code}
>  'yarn.nodemanager.aux-services': 'mapreduce_shuffle,spark_shuffle'
> {code}
