hadoop command uses large JVM heap size
---------------------------------------
Key: HADOOP-5564
URL: https://issues.apache.org/jira/browse/HADOOP-5564
Project: Hadoop Core
Issue Type: Bug
Reporter: Suresh Srinivas
Assignee: Suresh Srinivas
Fix For: 0.20.0
Command used to determine JAVA_PLATFORM in bin/hadoop command does not set the
heap size. The command uses default 1GB heap size. The tasks invoking hadoop
command end up using large heap size in streaming jobs. If the maximum memory
that can be used by a task is restricted, this could result in map/reduce job
failures.
