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.
M HMaster
Remove the silly stops in startup now we have real
means of shutting down Master during init.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/MasterMetaBootstrap.java
This replica stuff was doing stuff it shouldn't be doing
like setting core Master state flags. It may have made
sense once but now meta is assigned by a Pv2 Procedure
so the flag setting in here is meddlesome. Clear out
methods no longer needed.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Remove unused methods.
Changes local variable names so they align w/ our naming elsewhere in
code base.

Rename the PE Worker threads.
Send an interrupt if worker taking a long time to go down

This will make problems shutting down more obvious.
Disable TestRegionsOnMasterOptions. Master carrying Regions is broke.
Set the ProcedureExcecutor worker threads as daemon.
Ditto for the timeout thread.
Remove hack from TestRegionsOnMasterOptions that was
put in place because the test would not go down.
M dev-support/make_rc.sh
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.

previously by adding a latch to try and hold up superclass RegionServer
until cluster id set by subclass Master.
In some situations, Runtime.getRuntime().getAvailableProcessors()
may return 0 which would result in calculatePoolSize returning 0

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.

null from other coprocessor even on bypass
If 'bypass' is set by a Coprocessor, skip out on calling any subsequent
Coprocessors that might be chained to a bypassable method.
This patch restores some of the 'complete' behavior removed by
HBASE-19123 only 'bypass' now triggers 'complete'.
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
and performance impact that accompanied the previous
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
Update timeouts for TestRegionObserverInterface.
Reason: There are ~10 tests there, each with 5 min individual timeout. Too much. The test class is labelled MediumTests,
let's used that with our standard CategoryBasedTimeout. 3 min per test function should be enough even on slower Apache machines.
This avoids the situation where the build machine has sufficient disk
space (a few GB's at most) to run an HBase test, but the default YARN
configuration would preclude the NM's from starting correctly. This
should eliminate a trivial source of build flakiness based on the host
machines being used.

Use header and footer in our *.jsp pages to avoid unnecessary redundancy (copy-paste of code)

- Due to redundancy, new additions make it to some places but not others. For eg there are missing links to "/logLevel", "/processRS.jsp" in few places.
- Fix processMaster.jsp wrongly pointing to rs-status instead of master-status (probably due to copy paste from processRS.jsp)

- Renamed some classes to use a consistent naming for classes - ZK instead of mix of ZK, Zk , ZooKeeper. Couldn't rename following public classes: MiniZooKeeperCluster, ZooKeeperConnectionException. Left RecoverableZooKeeper for lack of better name. (suggestions?)
- Sadly, can't move tests out because they depend on HBaseTestingUtility (which defeats part of the purpose - trimming down hbase-server tests. We need to promote more use of mocks in our tests)

Last mockito-all release was in Dec'14. Mockito-core has had many releases since then.
From mockito's site:
- "Mockito does not produce the mockito-all artifact anymore ; this one was primarily
aimed at ant users, and contained other dependencies. We felt it was time to move on
and remove such artifacts as they cause problems in dependency management system like
maven or gradle."
- anyX() and any(SomeType.class) matchers now reject nulls and check type.
'bypass' logic case by case
Changes Coprocessor ObserverContext 'bypass' semantic. We flip the
default so bypass is NOT supported on Observer invocations; only a
couple of preXXX methods in RegionObserver allow it: e.g. preGet
and prePut but not preFlush, etc. Everywhere else, we throw
a DoesNotSupportBypassException if a Coprocessor Observer
tries to invoke bypass. Master Observers can no longer stop
or change move, split, assign, create table, etc.
Ditto on complete, the mechanism that allowed a Coprocessor
rule that all subsequent Coprocessors are skipped in an
invocation chain; now, complete is only available to
bypassable methods (and Coprocessors will get an exception if
they try to 'complete' when it is not allowed).
See javadoc for whether a Coprocessor Observer method supports
'bypass'. If no mention, 'bypass' is NOT supported.
M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/CoprocessorHost.java
Added passing of 'bypassable' (and 'completable') and default 'result' argument to
the Operation constructors rather than pass the excecution engine as parameters.
Makes it so can clean up RegionObserverHost and make the calling
clearer regards what is going on.
Methods that support 'bypass' must set this flag on the Observer.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegion.java
