Subject [jira] [Commented] (MAPREDUCE-6233) org.apache.hadoop.mapreduce.TestLargeSort.testLargeSort failed in trunk
Date Mon, 02 Feb 2015 00:07:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6233?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14300795#comment-14300795
] 

zhihai xu commented on MAPREDUCE-6233:
--------------------------------------

The error message is "Error: Java heap space"
The default MAP_MEMORY_MB is 1024m which is not big enough.
The test is passed if I increase MRJobConfig.MAP_MEMORY_MB to 2048m.
I submit a patch which set  MRJobConfig.MAP_MEMORY_MB to 2G for review.
