Subject Re: fairscheduler : group.name doesn't work, please help
Date Thu, 01 Mar 2012 17:54:54 GMT
The group.name scheduler support was introduced in
https://issues.apache.org/jira/browse/HADOOP-3892 but may have been
broken by the security changes present in 0.20.205. You'll need the
fix presented in  https://issues.apache.org/jira/browse/MAPREDUCE-2457
to have group.name support.
