Subject [jira] [Commented] (MAPREDUCE-2107) Emulate Memory Usage of Tasks in GridMix3
Date Wed, 04 May 2011 09:24:03 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2107?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13028681#comment-13028681

Ravi Gummadi commented on MAPREDUCE-2107:
-----------------------------------------

Am planning to emulate committed heap usage of the task JVM as a first step twards emulating
memory usage. This committed heap usage comes from MAPREDUCE-2469 into job history file and
then MAPREDUCE-2104 will bring that info into the trace file.

> MAPREDUCE-220 makes CPU/Memory usage of Tasks available in JobHistory files. Use this
> to emulate the memory usage of Tasks (of course, once MAPREDUCE-2104 is done).
