Eli Reisman commented on GIRAPH-730:
------------------------------------

Oops -- comment above seems to have cut off the top of my original text. Missing part:

I am uploading a "suggestion patch" in case Chaun is working something else now that does
what we talked about above -- just synchronize the creation of the LOCAL_RESOURCES map, not
every call to get a reference to it.

> In GiraphApplicationMaster.java, getTaskResourceMap function is not multi-thread safe,
which causes the application master fail to distribute the resources (jar, configuration file,
etc.) to each container.
