----------------------------------
Resolution: Fixed
Hadoop Flags: Reviewed
Fix Version/s: 1.4.0
1.3.0

Release Note: This adds a new per-region metric named
"lastMajorCompactionAge" for tracking time since the last major compaction ran
on a given region. If a major compaction has never run, the age will be equal
to the current timestamp.

> After HBASE-12859, we can now track the last major compaction timestamp for
> each region. However, this is only exposed through cluster status reporting
> and the admin API.
> We have similar per-region metrics around storefile age, but none that
> filters on major compaction specifically.
> Let's add a metric for last major compaction age.
