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.

Add extra step and run handleRIT a second time after we've queued up

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.
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.

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).
This de-couples the snapshot size calculation from the
SpaceQuotaObserverChore into another API which both the periodically
invoked Master chore and the Master service endpoint can invoke. This
allows for multiple sources of snapshot size to reported (from the
multiple sources we have in HBase).
When a file is archived, snapshot sizes can be more quickly realized and
the Master can still perform periodical computations of the total
snapshot size to account for any delayed/missing/lost file archival RPCs.

Master never left waitForMasterActive because it never checked state of
the clusterUp flag. The test here was aborting regionserver and then
just exiting. The minihbasecluster shutdown sets the cluster down flag
but we were never looking at it so Master thread was staying up.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
The tableOnMaster check in waitForMasterActive looks wrong. It was
making it so a 'normal' Master was getting stuck in here. This is not
the place to worry about tablesOnMaster. That is for the balancer to be
concerned with. There is a problem with Master hosting
system-tables-only. After further study, Master can carry regions like a
regionserver but making it so it carries system tables only is tricky
given meta assign happens ahead of all others which means that the
Master needs to have checked-in as a regionserver super early... It
needs work. Punted for now.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Mostly renaming so lists and maps of region infos have same name as they
have elsewhere in code base and cleaning up confusion that may arise
when we talk of servers-for-system-tables....It is talking about
something else in the code changes here that is other than the normal
understanding. It is about filtering regionservers by their version
numbers so we favor regions with higher version numbers. Needs to go
back up into the balancer.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/balancer/BaseLoadBalancer.java
It was possible for the Master to be given regions if no regionservers
available (as per the failing unit test in this case).
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
Minor reordering moving the waitForMasterActive later in the initialize
and wrapping each test in a check if we are to keep looping (which
checks cluster status flag).
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestAssignmentManagerMetrics.java
This was an old test from the days when Master carried system tables.
Updated test and fixed metrics. Metrics count the hbase:meta along with
the userspace region so upped expected numbers (previously the
hbase:meta was hosted on the master so metrics were not incremented).
M hbase-server/src/test/java/org/apache/hadoop/hbase/master/balancer/TestRegionsOnMasterOptions.java
I took a look at this test again but nope, needs a load of work still to
make it pass.
M hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/ZKUtil.java
Stop being so whiney.
Certain operations in HBase are known to directly affect
the utilization of tables on HDFS. When these actions
occur, we can circumvent the normal path and notify the
Master directly. This results in a much faster response to
changes in HDFS usage.
This requires FS scanning by the RS to be decoupled from
the reporting of sizes to the Master. An API inside each
RS is made so that any operation can hook into this call
in the face of other operations (e.g. compaction, flush,
bulk load).

Allow OPEN as a possible state when update region transition state.
Usually state is OPENING but if crash before finish step is completed,
on replay, master may have read that the state is OPEN from meta table
and so will think it open... When we replay the procedure finish, allow
that the region is already OPEN.
Fix MoveRandomRegionOfTableAction. It depended on old AM behavior.
Make it do explicit move as is required in AMv3; w/o it, it was just
closing region causing test to fail.

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.
