Review request for Ambari, Jaimin Jetly and Sumit Mohanty.
Bugs: AMBARI-14679
https://issues.apache.org/jira/browse/AMBARI-14679
Repository: ambari
Description
-------
When Spark is added later to a cluster with YARN deployed then yarn-site is not
modified.
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 shown is :
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'}
But with SPARK added, it should be :
'yarn.nodemanager.aux-services': 'mapreduce_shuffle,spark_shuffle'
Fix : Added the YARN property (yarn.nodemanager.aux-services,
yarn.nodemanager.aux-services.spark_shuffle.class) dependency on property
(spark.yarn.queue).
