Subject [jira] [Commented] (MAPREDUCE-6234) TestHighRamJob fails
Date Mon, 02 Feb 2015 21:19:34 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-6234?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14301947#comment-14301947
] 

Masatake Iwasaki commented on MAPREDUCE-6234:
---------------------------------------------

The cause of the test failure is the change of default value of {{mapreduce.map.memory.mb}}
and {{mapreduce.reduce.memory.mb}} by MAPREDUCE-5785. Though the default value defined in
mapred-default.xml from 1024 to -1 (which means turning on auto deriving from the value of
-Xmx in java.opts), {{MRJobConfig.DEFAULT_MAP_MEMORY_MB}} and {{MRJobConfig.DEFAULT_REDUCE_MEMORY_MB}}
are still 1024. Those are used in a few place such as the test in Gridmix.
