Balazs Meszaros c48dc02b76 HBASE-18106 Redo ProcedureInfo and LockInfo
Main changes:
- ProcedureInfo and LockInfo were removed, we use JSON instead of them
- Procedure and LockedResource are their server side equivalent
- Procedure protobuf state_data became obsolate, it is only kept for
reading previously written WAL
- Procedure protobuf contains a state_message field, which stores the internal
state messages (Any type instead of bytes)
- Procedure.serializeStateData and deserializeStateData were changed slightly
- Procedures internal states are available on client side
- Procedures are displayed on web UI and in shell in the following jruby format:
  { ID => '1', PARENT_ID = '-1', PARAMETERS => [ ..extra state information.. ] }

Michael Stack 43c4bc5761 HBASE-18723 [pom cleanup] Do a pass with dependency:analyze; remove unused and explicity list the dependencies we exploit
Do a pass with dependency:analyze; remove unused and
explicity list the dependencies we exploit.
Remove the parent dependencies set which had junit, mockito,
log4j, and findbugs annotations (had to put junit back
temporarily in subsequent version of this patch TODO). Listing in
parent set meant these libs were dependencies for all modules
which in practice was not the case. Edited all modules so
those that need any from this parent set now do explicit listing.

Ran the dependency:analyze over the project. Acted on most
suggested removals and requests for explicit listing. Some
grey areas remain around transitives that come in with
hadoop -needs better excludes, another project- and that
the dependency:analyze tool is not always accurate in its
reporting.

Michael Stack 5940f4224c HBASE-18551 [AMv2] UnassignProcedure and crashed regionservers
If an unassign is unable to communicate with its target server,
expire the server and then wait on a signal from ServerCrashProcedure
before proceeding. The unassign has lock on the region so no one else
can proceed till we complete. We prevent any subsequent assign from
running until logs have been split for crashed server.

In AssignProcedure, do not assign if table is DISABLING or DISABLED.

M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
 Change remoteCallFailed so it returns boolean on whether implementor
wants to stay suspended or not.

then wait on SCP to wake us up after it has processed logs for failed
server.

Michael Stack d5c6e11016 HBASE-17908 Upgrade guava
Pull in guava 22.0 by using the shaded version up in new hbase-thirdparty project.

In poms, exclude guava everywhere except on hadoop-common. Do this so
we minimize transitive includes. hadoop-common is needed because hadoop
Configuration uses guava doing preconditions.

Everywhere we used guava, instead use shaded so fix a load of imports.

Stopwatch API changed as did hashing and toStringHelper which is now
in MoreObjects class. Otherwise, minimal changes to come up on 22.0

Umesh Agashe 07c38e7165 HBASE-16549 Added new metrics for AMv2 procedures
Following AMv2 procedures are modified to override onSubmit(), onFinish() hooks provided by HBASE-17888 to do
metrics calculations when procedures are submitted and finshed:
* AssignProcedure
* UnassignProcedure
* MergeTableRegionProcedure
* SplitTableRegionProcedure
* ServerCrashProcedure

Following metrics is collected for each of the above procedure during lifetime of a process:
* Total number of requests submitted for a type of procedure
* Histogram of runtime in milliseconds for successfully completed procedures
* Total number of failed procedures

As we are moving away from Hadoop's metric2, hbase-metrics-api module is used for newly added metrics.

Modified existing tests to verify count of procedures.

Michael Stack 3975bbd008 HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi) Move to a new AssignmentManager, one that describes Assignment using a State Machine built on top of ProcedureV2 facility.
This doc. keeps state on where we are at w/ the new AM:
https://docs.google.com/document/d/1eVKa7FHdeoJ1-9o8yZcOTAQbv0u0bblBlCCzVSIn69g/edit#heading=h.vfdoxqut9lqn
Includes list of tests disabled by this patch with reasons why.

Based on patches from Matteos' repository and then fix up to get it all to pass cluster
tests, filling in some missing functionality, fix of findbugs, fixing bugs, etc..
including:

    1. HBASE-14616 Procedure v2 - Replace the old AM with the new AM.
    The basis comes from Matteo's repo here:
    689227fcbf

    Patch replaces old AM with the new under subpackage master.assignment.
    Mostly just updating classes to use new AM -- import changes -- rather
    than the old. It also removes old AM and supporting classes.
    See below for more detail.

    2. HBASE-14614 Procedure v2 - Core Assignment Manager (Matteo Bertozzi)
    3622cba4e3

    Adds running of remote procedure. Adds batching of remote calls.
    Adds support for assign/unassign in procedures. Adds version info
    reporting in rpc. Adds start of an AMv2.

    3. Reporting of remote RS version is from here:
    ddb4df3964.patch

    4. And remote dispatch of procedures is from:
    186b9e7c4d

    5. The split merge patches from here are also melded in:
    9a3a95a2c2
    and d6289307a0

We add testing util for new AM and new sets of tests.

Does a bunch of fixup on logging so its possible to follow a procedures' narrative by grepping
procedure id. We spewed loads of log too on big transitions such as master fail; fixed.

Fix CatalogTracker. Make it use Procedures doing clean up of Region data on split/merge.
Without these changes, ITBLL was failing at larger scale (3-4hours 5B rows) because we were
splitting split Regions among other things (CJ would run but wasn't
taking lock on Regions so havoc).

    Added a bunch of doc. on Procedure primitives.

    Added new region-based state machine base class. Moved region-based
    state machines on to it.

    Found bugs in the way procedure locking was doing in a few of the
    region-based Procedures. Having them all have same subclass helps here.

    Added isSplittable and isMergeable to the Region Interface.

    Master would split/merge even though the Regions still had
    references. Fixed it so Master asks RegionServer if Region
    is splittable.

    Messing more w/ logging. Made all procedures log the same and report
    the state the same; helps when logging is regular.

    Rewrote TestCatalogTracker. Enabled TestMergeTableRegionProcedure.

    Added more functionality to MockMasterServices so can use it doing
    standalone testing of Procedures (made TestCatalogTracker use it
    instead of its own version).

    Add to MasterServices ability to wait on Master being up -- makes
    it so can Mock Master and start to implement standalone split testing.
    Start in on a Split region standalone test in TestAM.

    Fix bug where a Split can fail because it comes in in the middle of
    a Move (by holding lock for duration of a Move).

    Breaks CPs that were watching merge/split. These are run by Master now
    so you need to observe on Master, not on RegionServer.

Umesh Agashe 5eb1b7b96c HBASE-18018 Changes to support abort for all procedures by default
The default behavior for abort() method of StateMachineProcedure is changed to support aborting all procedures irrespective of if rollback is supported or not. Currently its observed that sometimes procedures may fail on a step which will be considered as retryable error as abort is not supported. As a result procedure may stuck in a endless loop repeating same step again.User should have an option to abort any stuck procedure and do clean up manually. Please refer to HBASE-18016 and discussion there.

Apekshit Sharma 4d90425031 HBASE-17699 Fix TestLockProcedure.
Earlier when queues had locks, clearQueue() also cleaned up old locks when AbstractProcedureScheduler.clear() was called to reset scheduler for testing failure and recovery.
Now with locks decoupled from queues, they need to be separately cleaned up.
We can't have clearLocks() as abstract method in AbstractProcedureScheduler because at that level, a procedure scheduler is just a queue. It's only in MasterProcedureScheduler that locks come into picture. So directly overriding clear() method in MPS.

Apekshit Sharma 826b9436fb HBASE-17605 Changes
- Moved locks out of MasterProcedureScheduler#Queue. One Queue object is used for each namespace/table, which aren't more than 100. So we don't need complexity arising from all functionalities being in one place. SchemaLocking now owns locks and locking implementaion has been moved to procedure2 package.
- Removed NamespaceQueue because it wasn't being used as Queue (add,peek,poll,etc functions threw UnsupportedOperationException). It's was only used for locks on namespaces. Now that locks have been moved out of Queue class, it's not needed anymore.
- Remoed RegionEvent which was there only for locking on regions. Tables/namespaces used locking from Queue class and regions couldn't (there are no separate proc queue at region level), hence the redundance. Now that locking is separate, we can use the same for regions too.
- Removed QueueInterface class. No declarations, except one implementaion, which makes the point of having an interface moot.
- Removed QueueImpl, which was the only concrete implementation of abstract Queue class. Moved functions to Queue class itself to avoid unnecessary level in inheritance hierarchy.
- Removed ProcedureEventQueue class which was just a wrapper around ArrayDeque class. But we now have ProcedureWaitQueue as 'Type class'.
- Encapsulated table priority related stuff in a single class.
- Removed some unused functions.

Michael Stack 980c8c2047 HBASE-17067 Procedure v2 - remove zklock/tryLock and use wait/wake (Matteo Bertozzi)
This is an amalgam of https://reviews.apache.org/r/54435/ and
9c14863594

Removes notion of suspend/resume from procedure. Instead have the below lock states
and just unschedule if lock is not yet available

 LOCK_ACQUIRED should be returned when the proc has the lock and the proc is ready to execute.
 LOCK_YIELD_WAIT should be returned when the proc has not the lock and the framework
   should take care of readding the procedure back to the runnable set for retry
 LOCK_EVENT_WAIT should be returned when the proc has not the lock and someone will take care of
  readding the procedure back to the runnable set when the lock is available.

Side benefit is being able to undo a bunch of synchronization around
procedure management.
