Andrew Wang updated HDFS-5320:
------------------------------
Attachment: hdfs-5320-3.patch
New patch rebased on the FsDatasetCache changes. It's not much code, but I did
also choose to rename dnCacheCapacity/dnCacheUsed to just
cacheCapacity/cacheUsed for conciseness.
New tests check that the DN metrics tick up correctly, and I checked that
they're visible in /jmx too.
