stack commented on HBASE-1816:
------------------------------
Committed v4 above.
Does following:
+ Downs the retries when tests are running from 10 to 4.
+ Made the RegionManager and ServerManager public (but kept their constructors
package protected) so can live outside Master; made it so could get rid of a
bunch of redirection where methods were duplicated in Master and all they did
was go to RegionManager.
+ Removed unused data members and accessors in HMaster
+ Made all in HMaster private. Added accessors. Removed all mentions of
ServerManager from RegionManager but unable to do the reciprocal just yet.
There is really ugly stuff where in ServerManager, we'll sync on the
RegionManager and then do a bunch of RegionManager operations. Hopefully most
of these go when move table state and schema to zk.
+ Moved HMsg defines from ServerManager to HMsg where they belong
+ Cleaned up cruddy javadoc
+ Move fs methods out of HMaster to FSUtils.
+ Some cleanup of zk watchers. Moved method from HMaster out to zk master
watcher class
HMaster still too big.
Working on moving state and schema to zk now. Will do as per the design where
I write a JSON file that has an entry per table with state and schema
