Haohui Mai commented on HDFS-6156:
----------------------------------
Looks good to me. +1.
Nit: there are a bunch of trailing whitespace in the patch. I'll go ahead and
commit this patch using {{git apply --whitespace=fix}}, but it would be great
if the patch can be cleaned up next time.
> Simplify the JMX API that provides snapshot information

> HDFS-5196 introduces a set of new APIs that provide snapshot information
> through JMX. Currently. The API nests {{SnapshotDirectoryMXBean}} into
> {{SnapshotStatsMXBean}}, creating another layer of composition.
> This jira proposes to inline {{SnapshotDirectoryMXBean}} into
> {{SnapshotStatsMXBean}} and to simplify the API.
