Subject [jira] Created: (HADOOP-5564) hadoop command uses large JVM heap size
Date Tue, 24 Mar 2009 18:34:51 GMT
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.
