Description

Ambari is not exposing the heap size parameter for Spark History Server.
The workaround is to modify spark-env and add "SPARK_DAEMON_MEMORY=2g" for example.
The newer versions of Spark defaults this to 1g, but on the older versions, it was defaulting to 512m it seems, and it was causing OOM.
So in the patch, "SPARK_DAEMON_MEMORY=1G" is added in the spark-env template (default: 1G).
