* move hbaseanti import checks to checkstyle
* implment a few missing equals checks, and ignore one
* fix lots of javadoc errors

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.
- CacheStats won't generate NaN metrics.
- JSONBean class will serialize special floating point values as
"NaN", "Infinity" or "-Infinity"

Add method the CellComparator Interface. Add implementation to
meta comparator so we don't fall back to the default comparator.
Includes a nothing change to hbase-server/pom.xml just to provoke
build.
When we pread, we don't force the read to read all of the next block header.
However, when we get into a race condition where two opener threads try to
cache the same block and one thread read all of the next block header and
the other one didn't, it will fail the open process. This is especially important
in a splitting case where it will potentially fail the split process.
Instead, in the caches, we should only fail if the required blocks are different.

Change the MemStore size accounting so we don't synchronize across three
volatiles applying deltas. Instead:
+ Make MemStoreSize, a datastructure of our memstore size longs, immutable.
+ Undo MemStoreSizing being an instance of MemStoreSize; instead it has-a.
+ Make two MemStoreSizing implementations; one thread-safe, the other not.
+ Let all memory sizing longs run independent, untied by
synchronize (Huaxiang and Anoop suggestion) using atomiclongs.
+ Review all use of MemStoreSizing. Many are single-threaded and do
not need to be synchronized; use the non-thread safe counter.
TODO: Use this technique accounting at the global level too.
Add backoff when stuck in RegionTransitionProcedure, the subclass of
AssignProcedure and UnassignProcedure. Can happen when we go to
transition but the current Region state is not what we expect.
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/Procedure.java
Add doc on being able to suspend and wait on a timeout.
M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto
Add 'attempt' counter so we can do backoff when we get stuck.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignProcedure.java
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java
Add persistence of new 'attempt' counter
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
Doc data members that are persisted by subclasses given this is 'odd'.
Add a counter for 'attempts' used when 'stuck' to implement backoff.
Add suspend with timeout when 'stuck'. Add callback when timeout is
exhausted which does wakeup of this procedure.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestUnexpectedStateException.java
Test of backoff.
Fix test that depended upon flush being slow and one family only.
Fix MemStoreSize compare to allow passing alternate implementation
(needed when IMC was no longer default everywhere).
HBase server versioned is checked after connecting to the server and then following operations are not allowed:
-fix, -fixAssignments, -fixMeta, -fixHdfsHoles, -fixHdfsOrphans, -fixTableOrphans, -fixHdfsOverlaps, -maxMerge
-sidelineBigOverlaps, -maxOverlapsToSideline, -fixSplitParents, -removeParents, -fixEmptyMetaCells

* Make CleanerChore less chatty: move WARN message to DEBUG when we expect non-empty dirs
* Make CleanerChore less chatty: move IOE we'll retry to INFO
* CleanerChore should treat IOE for FileStatus as a failure
* Add tests asserting assumptions in above

in-memory-compaction logging
Adds logging of CompactingMemStore configuration on construction.
Add logging of detail about Store on creation including memstore type.
Add chapter to refguide on new in-memory compaction feature.
When prefetch on open is specified, there is a deadlocking case
where if the prefetch is cancelled, the PrefetchExecutor interrupts
the threads if necessary, when that happens in FileIOEngine, it
causes an ClosedByInterruptException which is a subclass of
ClosedChannelException. If we retry all ClosedChannelExceptions,
this will lock as this access is expected to be interrupted.
This change removes calling refreshFileConnections for
ClosedByInterruptExceptions.

The Master asks a RegionServer whether a Region can be split or not, primarily to
verify that the region is not closing, opening, etc. This change has the RegionServer
also consult the configured RegionSplitPolicy.

Changes for HBASE-20027 seem to cause UI not showing up on default port in standalone mode. For concurrent
unit test execution, individual tests can set hbase.localcluster.assign.random.ports to true or modify
test/resources/hbase-site.xml.

Adds a prepare step to RecoverMetaProcedure in which we test for
cluster up and master being up. If not up, we fail the run.
Modified hbase-server/src/main/java/org/apache/hadoop/hbase/master/cleaner/HFileCleaner.java
Modified hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ChunkCreator.java
Minor log cleanup.

Added hbase-server/src/test/java/org/apache/hadoop/hbase/master/procedure/TestRecoverMetaProcedure.java
Test the prepare step goes down if master or cluster are down.

Log less. Log using same format as used elsewhere in log.
Align logs in HFileArchiver with how we format elsewhere. Removed
redundant 'region' qualifiers, tried to tighten up the emissions so
easier to read the long lines.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/ChunkCreator.java
Add a label for each of the chunkcreators we make (I was confused by
two chunk creater stats emissions in log file -- didn't know that one
was for data and the other index).
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CompactSplit.java
Formatting. Log less.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/MemStoreCompactionStrategy.java
Make the emissions in here trace-level. When more than a few regions,
log is filled with this stuff.
HBASE-19435 implements a fix for reopening file channels when they are unnexpected closed
to avoid disabling the BucketCache. However, it was missed that the the channels might not
actually be completely closed (the write or read channel might still be open
(see https://docs.oracle.com/javase/7/docs/api/java/nio/channels/ClosedChannelException.html)
This commit closes any open channels before creating a new channel.
