Siddharth Seth commented on MAPREDUCE-2691:
-------------------------------------------
The patch is really just fixing two things - related to distributed cache
cleanup.
- The reference list for resources was never being cleaned up - as a result
distributed cache cleanup would remove nothing.
- Size of private resources was not being computed correctly (always 0).
It doesn't look like an LRU cleanup is implemented, which i believe was added
recently to 20security - that would be a separate jira.
There's other stuff in the NM which needs fixing - but isn't necessarily
related to the distributed cache and this jira.
> Finish up the cleanup of distributed cache file resources and related tests.
