Jitendra Nath Pandey commented on HDFS-6919:
--------------------------------------------
I am planning to merge HDFS-6581 work to branch-2 today, and subsequently to
branch-2.6 by tomorrow. As suggested earlier, in 2.6 we will indicate in the
release notes that the memory for writes on RAM and the memory for caching in
datanodes are independent, and a feature to manage them together will be added
in the next release.
> Enforce a single limit for RAM disk usage and replicas cached via locking
