Subject [jira] [Commented] (MAPREDUCE-2328) memory-related configurations missing from mapred-default.xml
Date Thu, 12 May 2011 07:45:47 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-2328?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13032293#comment-13032293
] 

Todd Lipcon commented on MAPREDUCE-2328:
----------------------------------------

Seems we are still missing mapreduce.map.memory.mb, mapreduce.map.memory.physical.mb, etc
from mapred-default.xml.

I think the descriptions could also be improved. Take a look at src/docs/src/documentation/content/xdocs/cluster_setup.xml
in the common repo for pretty good descriptions, as well as [this comment|https://issues.apache.org/jira/browse/HADOOP-5881?focusedCommentId=12712751&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-12712751].
