             Summary: YARN executors are launched with the default perm gen size
                 Key: SPARK-10916
                 URL: https://issues.apache.org/jira/browse/SPARK-10916
             Project: Spark
          Issue Type: Bug
          Components: YARN
    Affects Versions: 1.5.1, 1.6.0
            Reporter: Marcelo Vanzin


Unlike other backends, the YARN one does not explicitly set the perm gen size 
for the executor process. That means that, unless the user has explicitly 
changed it by adding extra java options, executors on YARN are running with 64m 
of perm gen (I believe) instead of 256m like the other backends.
