On failed RPC we expire the server and suspend expecting the
resultant ServerCrashProcedure to wake us back up again. In tests,
TestRSGroup hung because it failed to schedule a server expiration
because the server was already expired undergoing processing (the
test was shutting down). Deal with this case by having expire
servers return false if unable to expire. Callers will then know
where a ServerCrashProcedure has been scheduled or not.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/ServerManager.java
Have expireServer return true if successful.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
The log that included an exception whose message was the current
procedure as a String totally baffled me. Make it more obvious what
exception is.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java
If failed expire of a server, wake our procedure -- do not suspend --
and presume ok to move region to CLOSED state (because going down or
concurrent crashed server processing ongoing).

Allow OPEN as a possible state when update region transition state.

- Added ADMIN permission check for following rpc calls:
normalize, setNormalizerRunning, runCatalogScan, enableCatalogJanitor, runCleanerChore,
setCleanerChoreRunning, execMasterService, execProcedure, execProcedureWithRet
- Moved authorizationEnabled check to start of AccessChecker's functions. Currently, and IDK why,
we call authManager.authorize() first and then discard its result if authorizationEnabled is false. Weird.
Negative Remaining KVs and progress percent greater than 100 is because CompactionProgress#totalCompactingKVs is sometimes less than CompactionProgress#currentCompactedKVs.
Changes add a getter to CompactionProgress#totalCompactingKVs and from inside getter warning is logged. currentCompactedKVs are return when totalCompactingKVs are less than current.

Revert "Revert "HBASE-2004 TestClientClusterStatus is flakey""
This is a revert of a revert, i.e. a reapplication, just so I can fix
the JIRA number.
This reverts commit 6796b8e21f.
LocalHBaseCluster forces random port assignment for sake of concurrent unit test
execution friendliness, but we still need a positive test for RPC and info port
assignment.
The 1.x functionality of Master DDL operations is that "post" observer hooks
are only invoked when the DDL action was successful. With the async-ness of
ProcV2, we find ourselves in a case where the post-hook may be invoked before
the Procedure runs and fails. We need to introduce some blocking to wait and
see if the Procedure is going to fail on a precondition before invoking the hook.

Remove assert in splittableregionprocedure. It was in the prepare.
Was causing fail in legit case where a region split follows a
table split BEFORE the parent has been GC'd. The region split
finds the parent in SPLIT state which is right. The assert was
having us fail. No need.
Also disabled TestHTrace since not supported in 2.0.0 and flakey.
Only call server.checkIfShouldMoveSystemRegionAsync if a node has been
added. Do not call it if only one regionserver in cluster. Make it
so ServerCrashProcedure runs before it. Add logging if
server.checkIfShouldMoveSystemRegionAsync was responsible for
MOVE (Previous was a mystery when it cut in).
Previous we'd call it when there was a nodeChildrenChanged. These
happen before nodeDeleted. If a server crashed,
checkIfShouldMoveSystemRegionAsync could run first, find the
server that had not yet registered as crashed, find system
tables on it and then try to move them. It would fail because
server would not respond to RPC. The region move would then
be waiting on the servercrashprocedure to wake it up when
done processing but this move had locked the region so
SCP couldn't run....
Serializing, if appropriate, write the hbase-1.x version of the
Comparator to the hfile trailer so hbase-1.x files can read hbase-2.x
hfiles (they are the same format).
This patch adds mirroring of table state out to zookeeper. HBase-1.x
clients look for table state in zookeeper, not in hbase:meta where
hbase-2.x maintains table state.
The patch also moves and refactors the 'migration' code that was put in
place by HBASE-13032.

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.

like setting core Master state flags. It may have made
sense once but now meta is assigned by a Pv2 Procedure

methods no longer needed.

Disable checkstyle building site. Its an issue being fixed over in HBASE-19780
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
The clusterid was being set into the process only after the
regionserver registers with the Master. That can be too late for some
test clients in particular. e.g. TestZKAsyncRegistry needs it as soon
as it goes to run which could be before Master had called its run
method which is regionserver run method which then calls back to the
master to register itself... and only then do we set the clusterid.
HBASE-19694 changed start order which made it so this test failed.
Setting the clusterid right after we set it in zk makes the test pass.
Another change was that backup masters were not going down on stop.
Backup masters were sleeping for the default zk period which is 90
seconds. They were not being woken up to check for stop. On stop
master now tells active master manager.

Reenables the test. Adds facility to HBaseTestingUtility so
you can pass in ports a restarted cluster should use. This
is needed so retention of region placement, on which this
test depends, can come trigger (this is why it was broke
on AMv2 commit... region placement retention is done
different in AMv2).
Added new bulk assign createRoundRobinAssignProcedure to complement
the existing createAssignProcedure. The former asks the balancer for
target servers to set into the created AssignProcedures. The latter
sets no target server into AssignProcedure. When no target server
is specified, we make effort at assign-time at trying to deploy the
region to its old location if there was one.
The new round robin assign procedure creator does not do this. Use
the new round robin method on table create or reenabling offline
regions. Use the old assign in ServerCrashProcedure or in
EnableTable so there is a chance we retain locality.
Bulk preassigning passing all to-be-assigned to the balancer in one
go is good for ensuring good distribution especially when read
replicas in the mix.
The old assign was single-assign scoped so region replicas could
end up on the same server.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignProcedure.java
Cleanup around forceNewPlan. Was confusing.
Added a Comparator to sort AssignProcedures so meta and system tables

Remove the forceNewPlan argument on createAssignProcedure. Didn't make
sense given we were creating a new AssignProcedure; the arg had no
effect.
(createRoundRobinAssignProcedures) Recast to feed all regions to the balancer in
bulk and to sort the return so meta and system tables take precedence.
Miscellaneous fixes including keeping the Master around until all
RegionServers are down, documentation on how assignment retention
works, etc.

For a egionserver's view of a table (the regions
that belong to a table hosted on a regionserver),
this change tracks the latencies of operations that
affect the regions for this table.
Tracking at the per-table level avoids the memory bloat

per-region latency metrics while still providing important
details for operators to consume.

- Adding javadoc comments
- Bug: ServerStateNode#regions is HashSet but there's no synchronization to prevent concurrent addRegion/removeRegion. Let's use concurrent set instead.
- Use getRegionsInTransitionCount() directly to avoid instead of getRegionsInTransition().size() because the latter copies everything into a new array - what a waste for just the size.
- There's mixed use of getRegionNode and getRegionStateNode for same return type - RegionStateNode. Changing everything to getRegionStateNode. Similarly rename other *RegionNode() fns to *RegionStateNode().
- RegionStateNode#transitionState() return value is useless since it always returns it's first param.
- Other minor improvements
It seems like the original reason this execution filter was added is no
longer an issue for 2.0. Actually, these entries actually preclude
Eclipse from correctly using the Java8 source/target version that we
