[jira] [Commented] (MAPREDUCE-5650) Job fails when hprof
mapreduce.task.profile.map/reduce.params is specified
[ https://issues.apache.org/jira/browse/MAPREDUCE-5650?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13850985#comment-13850985 ]
Sandy Ryza commented on MAPREDUCE-5650:
---------------------------------------
If I understand correctly, the issue is that the default (mapreduce.task.profile.params) params will be supplied even when more specific params are specified. Was the behavior different in MR1? Want to make sure this is not an incompatible change.

> When one uses dedicated hprof mapreduce.task.profile.map.params or mapreduce.task.profile.reduce.params, the profiled tasks will fail to launch because hprof parameters are supplied to the child jvm twice.
