[jira] Resolved: (HADOOP-468) Setting scheduling priority in
hadoop-env.sh
[ http://issues.apache.org/jira/browse/HADOOP-468?page=all ]
Doug Cutting resolved HADOOP-468.
---------------------------------
Fix Version/s: 0.6.0
Resolution: Fixed
I just committed this. I renamed the environment variable from HADOOP_NICE_VALUE to HADOOP_NICENESS, and also added an entry to hadoop-env.sh.template. (hadoop-env.sh is not in svn, so that user modifications to it are not overwritten. Instead we copy such files from a template file at build time.)
Thanks, Vetle!

> 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?
