Review request for hbase, stack and khemani.
Changes
-------
Latest version. I guess I should write some tests...
Summary
-------
This is a somewhat misguided attempt. It's not done but it shows the fairly
simple change to the actual major compaction code.
The hard part is:
+ long lastMajor = region.getRegionInfo().getRegionData().getLastMajor();
And the question is where to persist that.
This patch adds a new class called HRegionData into HRegionInfo that contains
any number of key-value pairs of data that get persisted with the HRI. Not
really sure how I ended up there but this data seemed like an odd-man-out so
adding another field seemed weird. We also need some kind of versioning in HRI
so we can add stuff w/o migrating. There's some versioned stuff in HRData.
Just looking for some feedback / ideas.
This addresses bugs HBASE-2990 and HBASE-3083.
