Subject [jira] Commented: (HADOOP-3759) Provide ability to run memory intensive jobs without affecting other running tasks on the nodes
Date Wed, 20 Aug 2008 07:06:44 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-3759?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12623917#action_12623917

Hemanth Yamijala commented on HADOOP-3759:
------------------------------------------

+1 from me too. Since there is consensus on keeping the ulimit method, I've reverted the changes
and uploaded a new patch. Will submit this to Hudson, as all comments have been taken care
of now.

> In HADOOP-3581, we are discussing how to prevent memory intensive tasks from affecting
Hadoop daemons and other tasks running on a node. A related requirement is that users be provided
an ability to run jobs which are memory intensive. The system must provide enough knobs to
allow such jobs to be run while still maintaining the requirements of HADOOP-3581.
