ModifyTableProcedure is using MoveRegionProcedure in a way
that was unintended from the original implementation. As such,
we have to guard against certain usages of it. We know we can
re-open OPEN regions, but regions in OPENING will similarly
soon be OPEN (thus, we want to reopen those regions too).

A reattempt at fixing HBASE-20173 [AMv2] DisableTableProcedure concurrent to ServerCrashProcedure can deadlock
The scenario is a SCP after processing WALs, goes to assign regions that
were on the crashed server but a concurrent Procedure gets in there
first and tries to unassign a region that was on the crashed server
(could be part of a move procedure or a disable table, etc.). The
unassign happens to run AFTER SCP has released all RPCs that
were going against the crashed server. The unassign fails because the
server is crashed. The unassign used to suspend itself only it would
never be woken up because the server it was going against had already
been processed. Worse, the SCP could not make progress because the
unassign was suspended with the lock on a region that it wanted to
assign held making it so it could make no progress.
In here, we add to the unassign recognition of the state where it is
running post SCP cleanup of RPCs. If present, unassign moves to finish
instead of suspending itself.
Includes a nice unit test made by Duo Zhang that reproduces nicely the
hung scenario.

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.

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

Only call server.checkIfShouldMoveSystemRegionAsync if a node has been

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....

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

assignment. They need work.

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.
M hbase-server/src/test/java/org/apache/hadoop/hbase/TestJMXConnectorServer.java
Prevent creation of acl table. Messes up our being able to go down
promptly.
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestRegionsOnMasterOptions.java
M hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestMultiParallel.java
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestRegionServerReadRequestMetrics.java
Disabled for now because it wants to run with regions on the Master...
currently broke!
M hbase-server/src/test/java/org/apache/hadoop/hbase/client/TestZKAsyncRegistry.java
Add a bit of debugging.
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestDLSAsyncFSWAL.java
Disabled. Fails 40% of the time.
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestDLSFSHLog.java
Disabled. Fails 33% of the time.
Disabled stochastic load balancer for favored nodes because it fails on
occasion and we are not doing favored nodes in branch-2.
Become active Master before calling the super class's run method. Have
the wait-on-becoming-active-Master be in-line rather than off in a
background thread (i.e. undo running thread in startActiveMasterManager)
Purge the fragile HBASE-16367 hackery that attempted to fix this issue
previously by adding a latch to try and hold up superclass RegionServer
until cluster id set by subclass Master.
