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.

Remove commons-cli and commons-collections4 use. Account
for the newer internal protobuf version of 3.5.1.

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.
Modified hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/RecoverMetaProcedure.java
Add pepare step.
Modified hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestAssignmentManagerMetrics.java
Debug for the failing test....
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.
in-memory compactions)
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.

Allow passing cause to Constructor.
M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto
Add prepare step to move procedure.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/MergeTableRegionsProcedure.java
Add check that regions to merge are actually online to the Constructor
so we can fail fast if they are offline
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/MoveRegionProcedure.java
Add prepare step. Check regions and context and skip move if not right.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/SplitTableRegionProcedure.java
Add check parent region is online to constructor.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/AbstractStateMachineTableProcedure.java
Add generic check region is online utility function for use by subclasses.
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestRegionMove.java
Add test that we fail if we try to move an offlined region.
Add Fail-Fast to Procedures by throwing exception out of Procedure
constructor so if move but table is disabled or if master is going
down, etc., we can give notice before the procedure is scheduled.
Will help guard against scheduling Procedures that will have a hard
time succeeding; e.g. a move when table is offline.
Also fixed bug around table state where we presumed ENABLED though no
entry in hbase:meta (we were using this mechanism for whether a table
existed or not).

Do environment check at construction and fail-fast if hostile.

Add preflightCheck utility method.
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Removed setting time setting table state; broke when using other than
default environment edge masked by presumption that no state meant
active.
Allow that DisableTableProcedue can grab a region lock before
ServerCrashProcedure can. Cater to this cricumstance where SCP
was not unable to make progress by running the search for RIT
against the crashed server a second time, post creation of all
crashed-server assignemnts. The second run will uncover such as
the above DisableTableProcedure unassign and will interrupt its
suspend allowing both procedures to make progress.
M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto
Add new procedure step post-assigns that reruns the RIT finder method.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Make this important log more specific as to what is going on.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java
Better explanation as to what is going on.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/ServerCrashProcedure.java
Add extra step and run handleRIT a second time after we've queued up
all SCP assigns. Also fix a but. SCP was adding an assign of a RIT
that was actually trying to unassign (made the deadlock more likely).
We assumed that we can run for loop from 0 to lastStep sequentially. MergeTableRegionProcedure skips step 2. So, when i is 0 the procedure is already at step 3.
Added a method StateMachineProcedure#getCurrentStateId that can be used from test code only.
