Make it so hbase:meta can be altered. TableState for hbase:meta
is kept in Master. State is in-memory transient so if Master
fails, hbase:meta is ENABLED again. hbase:meta schema will be
bootstrapped from the filesystem. Changes to filesystem schema
are atomic so we should be ok if Master fails mid-edit (TBD)
Undoes a bunch of guards that prevented our being able to edit
hbase:meta. At minimmum, need to add in a bunch of WARNING.

Makes MergeTableRegionsProcedure do more than just two regions at a
time. Compatible as MTRP was done considering one day it'd do more than
two at a time.
Changes hardcoded assumption that merge parent regions are named
mergeA and mergeB in a column on the resultant region. Instead
can have N columns on the merged region, one for each parent
merged. Column qualifiers all being with 'merge'.
Most of code below is undoing the assumption that there are two
parents on a merge only.
Refactor of CatalogJanitor so it generates a
Report on the state of hbase:meta when it runs. Also
refactor so CJ runs even if RIT (previous it would
punt on running if RIT) so it can generate a 'Report'
on the interval regardless. If RIT, it just doesn't
go on to do the merge/split GC as it used to.
If report finds an issue, dump as a WARN message
to the master log.
Follow-on is to make the Report actionable/available
for the Master to pull when it goes to draw the hbck
UI page (could also consider shipping the Report as
part of ClusterMetrics?)
Adds new, fatter Visitor to CJ, one that generates
Report on each run keeping around more findings as
it runs.
Moved some methods around so class reads better;
previous methods were randomly ordered in the class.
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Make a few handy methods public.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RegionInfo.java
Add utility as defaults on the Inteface; i.e. is this the first region
in table, is it last, does a passed region come next, or does passed
region overlap this region (added tests for this new stuff).
M hbase-common/src/main/java/org/apache/hadoop/hbase/util/Bytes.java
Bugfix... handle case where buffer passed is null.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java
Lots of change, reorg., but mostly adding consistency checking

generation of a Report on what the scan has found traversing
hbase:meta. Added a main so could try the CatalogJanitor against
a running cluster.

Adds new stripped-down, faster ByteBufferKeyValue comparator
(BBKV is the base Cell-type in hbase2). Creates an instance
of new Comparator each time we create new memstore rather
than use the universal CellComparator.
Remove unused and unneeded Interfaces from Cell base type.
Run meta tests but using our new basis, the ByteBufferKeyValue
instead of the old byte array-backed KeyValue so we catch any
oddness in the Type processing or in the Comparator.
- CacheStats won't generate NaN metrics.
- JSONBean class will serialize special floating point values as

hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/Segment.java
patch reverted changes that happened in parallel without explanation. see jira.
Fix two issues:
# Meta Replicas can all be assigned to the same server. This
will call the test to hang when we do our kill of the server
hosting meta because there'll be no replicas to read from
as test intends. Check is to look for this condition on
startup and adjust if we come across it. Replicas cross-cut
assignment. They need work.
# Other issue was shutdown. The master started toward the
end of the test may not have come up fully by the time
shutdown is called. We could be stuck assigning the
meta replicas. Have shutdown shutdown the procedure
executor engine.
There is other cleanup and notes in the below.
M HMaster
Remove the silly stops in startup now we have real
means of shutting down Master during init.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterMetaBootstrap.java
This replica stuff was doing stuff it shouldn't be doing
like setting core Master state flags. It may have made
sense once but now meta is assigned by a Pv2 Procedure
so the flag setting in here is meddlesome. Clear out
methods no longer needed.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Remove unused methods.
Changes local variable names so they align w/ our naming elsewhere in
code base.
M hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestMetaWithReplicas.java

- log.XXX(Object) calls were replaced with log.XXX(Objects.toString(obj))
- log.fatal() calls were replaced with log.error(HBaseMarkers.FATAL, ...)
- programmatic log4j configuration was removed from the unit test
This commit does not affect the current logging configurations, because log4j
is still on the classpath. slf4j-log4j12 binds log4j to slf4j.

Last mockito-all release was in Dec'14. Mockito-core has had many releases since then.
From mockito's site:
- "Mockito does not produce the mockito-all artifact anymore ; this one was primarily
aimed at ant users, and contained other dependencies. We felt it was time to move on
and remove such artifacts as they cause problems in dependency management system like
maven or gradle."
- anyX() and any(SomeType.class) matchers now reject nulls and check type.
- Merged BaseCSM class into CSM interface
- Removed config hbase.coordinated.state.manager.class
- Since state manager is not pluggable anymore, we don't need start/stop/initialize to setup unknown classes. Our internal ZkCSM now requires Server in constructor itself. Makes the dependency clearer too.
- Removed CSM from HRegionServer and HMaster constructor. Although it's a step back from dependency injection, but it's more consistent with our current (not good) pattern where we initialize everything in the ctor itself.
