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

* rely on git plumbing commands when checking if we've built the site for a particular commit already
* switch to forcing '-e' for bash
* add command line switches for: path to hbase, working directory, and publishing
* only export JAVA/MAVEN HOME if they aren't already set.
* add some docs about assumptions
* Update javadoc plugin to consistently be version 3.0.0
* avoid duplicative site invocations on reactor modules
* update use of cp command so it works both on linux and mac
* manually skip enforcer plugin during build
* still doing install of all jars due to MJAVADOC-490, but then skip rebuilding during aggregate reports.
* avoid the pager on git-diff by teeing to a log file, which also helps later reviewing in the case of big changesets.

This patch adds mirroring of table state out to zookeeper. HBase-1.x

Changes:
- replaced commons-logging to slf4j everywhere
- log.XXX(Throwable) calls were replaced with log.XXX(t.toString(), t)
- log.XXX(Object) calls were replaced with log.XXX(Objects.toString(obj))
- log.fatal() calls were replaced with log.error(HBaseMarkers.FATAL, ...)
- programmatic log4j configuration was removed from the unit test
This commit does not affect the current logging configurations, because log4j
is still on the classpath. slf4j-log4j12 binds log4j to slf4j.

- 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:

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.
* Modified AssignmentManager.processAssignQueue() method to consider only highest versioned region servers for system table regions when

* Modified MoveRegionProcedure to allow null value for destination server i.e. moving a region from specific source server to non-specific/ unknown
destination server (picked by load-balancer) is supported now.
* Removed destination server selection from HMaster.checkIfShouldMoveSystemRegionAsync(), as destination server will be picked by load balancer

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.

Most notable change is to cache SpaceViolationPolicyEnforcement objects
in the write path. When a table has no quota or there is not SpaceQuotaSnapshot
for that table (yet), we want to avoid creating lots of
SpaceViolationPolicyEnforcement instances, caching one instance
instead. This will help reduce GC pressure.
A couple of variables and comments in which violation is incorrectly
used to describe what the code is doing. This was a hold over from early
implementation -- need to scrub these out for clarity.
Create some RPCs that can expose the in-memory state that the
RegionServers and Master hold to drive the space quota "state machine".
Then, create some hbase shell commands to interact with those.
The nuts-and-bolts of filesystem quotas. The Master must inform
RegionServers of the violation of a quota by a table. The RegionServer
must apply the violation policy as configured. Need to ensure
that the proper interfaces exist to satisfy all necessary policies.
This required a massive rewrite of the internal tracking by
the general space quota feature. Instead of tracking "violations",
we need to start tracking "usage". This allows us to make the decision
at the RegionServer level as to when the files in a bulk load request
should be accept or rejected which ultimately lets us avoid bulk loads
dramatically exceeding a configured space quota.

This reverts commit 8847a70902.
We committed two 'attempted fixes'. This is a revert of the first
attempt. It did not work. Sorry for confusion. I used the same
commit message so it could be awkward unraveling.
Rely on the new plugin to do all proto generation. No need of an
external protoc setup anymore. Mvn will do it all for you.
Updated all READMEs appropriately.

This patch changes poms to use protobuf-maven-plugin instaed of
hadoop-maven-plugins generating protos. Adds a few missing READMEs too
as well as purge of unused protos turned up by the new plugin.
Restore this change but with a clean of the generated dirs first so
that we avoid trying to apply a patch on top of an already patched src.
This reverts commit 0f384158fc.
Adds means of patching our shaded protobuf. Does it using
the Anoop patch attached to HBASE-15789 that adds ByteInput
to protobuf. This patch gets applied after protobuf has been
downloaded, relocated, and then unpacked over src/main/java.
Also fixes a few small build WARNINGs because of duplicate
mentions of dependencies.
