Subject [jira] Commented: (HADOOP-5881) Simplify configuration related to task-memory-monitoring and memory-based scheduling
Date Tue, 06 Apr 2010 03:32:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-5881?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12853717#action_12853717

Vinod K V commented on HADOOP-5881:
-----------------------------------

Are you using *all* the configuration items properly as documented [here|https://issues.apache.org/jira/browse/HADOOP-5881?focusedCommentId=12712919&page=com.atlassian.jira.plugin.system.issuetabpanels%3Acomment-tabpanel#action_12712919]
? You should be setting all of them with appropriate values.

The first error you mentioned seems to happening because you only configured the max limits
but not the cluster wide slot size and the per-job configuration.

No idea about the second problem. If you give more details, we can see.

We have been using this feature with the mentioned configuration items so far without any
issues, so I don't think there is any problem of using bytes vs MB at all.

> The configuration we have now is pretty complicated. Besides everything else, the mechanism
of not specifying parameters separately for maps and reduces leads to problems like HADOOP-5811.
This JIRA should address simplifying things and at the same time solving these problems.
