Eli Reisman updated GIRAPH-730:
-------------------------------

    Attachment: GIRAPH-730-2.patch

I'll upload the patch here, but if Chaun is still working this problem, I'm happy to leave it to him to fix this problem. I am in agreement now that if we catch this fix at the getTaskResourceMap() level we can solve the problem for now. Great work, Chaun!

One issue: i'm having trouble building Giraph (under any profile, even default) right now to test this...is the build broken right now? I'm on a clean trunk repo...?

> 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.
