[ http://issues.apache.org/jira/browse/HADOOP-468?page=comments#action_12429505 ] Doug Cutting commented on HADOOP-468: -------------------------------------
I think this would be a useful feature to have. Two nits with the patch: I think it will be easier to maintain if we set HADOOP_NICE_VALUE to zero by default and then only have a single invocation of bin/hadoop in the script, now with 'nice'. Since that command line is rather central and likely to be further changed, it's better to not have it replicated. Also we should document the new environment variable in the file header. > Setting scheduling priority in hadoop-env.sh > -------------------------------------------- > > Key: HADOOP-468 > URL: http://issues.apache.org/jira/browse/HADOOP-468 > Project: Hadoop > Issue Type: Improvement > Affects Versions: 0.5.0 > Reporter: Vetle Roeim > Priority: Minor > Attachments: sched_priority.diff > > > It is not possible to set the scheduling priority in the Hadoop > configuration. Attached is a patch for starting the Hadoop daemons through > nice with the configured priority (can be configured in conf/hadoop-env.sh, > for instance). > I would have included a patch for conf/hadoop-env.sh as well, but it seems to > be ignored? -- This message is automatically generated by JIRA. - If you think it was sent incorrectly contact one of the administrators: http://issues.apache.org/jira/secure/Administrators.jspa - For more information on JIRA, see: http://www.atlassian.com/software/jira
