Subject [jira] Resolved: (HADOOP-468) Setting scheduling priority in hadoop-env.sh
Date Wed, 23 Aug 2006 16:51:15 GMT
     [ 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?
