----------------------------------------

             Summary: When Spark is added later to a cluster with YARN deployed then yarn-site is not modified
                 Key: AMBARI-14679
                 URL: https://issues.apache.org/jira/browse/AMBARI-14679
             Project: Ambari
          Issue Type: Bug
          Components: ambari-server
    Affects Versions: 2.2.1
            Reporter: Swapan Shridhar
            Assignee: Swapan Shridhar
            Priority: Critical
             Fix For: 2.2.1


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.
It seems that recommendation provides it:

{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}


With SPARK added, it should be :

 'yarn.nodemanager.aux-services': 'mapreduce_shuffle,spark_shuffle'
