Siqi Li updated YARN-2730:
--------------------------
Description:
We are seeing that when one of the localizerRunner stuck, the rest of the
localizerRunners are blocked. We should remove the synchronized modifier.
The synchronized modifier appears to have been added by
https://issues.apache.org/jira/browse/MAPREDUCE-3537
It could be removed if Localizer doesn't depend on current directory
