- Merged BaseCSM class into CSM interface
- Removed config hbase.coordinated.state.manager.class
- Since state manager is not pluggable anymore, we don't need start/stop/initialize to setup unknown classes. Our internal ZkCSM now requires Server in constructor itself. Makes the dependency clearer too.
- Removed CSM from HRegionServer and HMaster constructor. Although it's a step back from dependency injection, but it's more consistent with our current (not good) pattern where we initialize everything in the ctor itself.

Breaks MemStoreSize into MemStoreSize (read-only) and MemStoreSizing
(read/write). MemStoreSize we allow to Coprocesors. MemStoreSizing we
use internally doing MemStore accounting.
Patch to start a standalone RegionServer that register's itself and
optionally stands up Services. Can work w/o a Master in the mix.
Useful testing. Also can be used by hbase-indexer to put up a
Replication sink that extends public-facing APIs w/o need to extend
internals. See JIRA release note for detail.
This patch adds booleans for whether to start Admin and Client Service.
Other refactoring moves all thread and service start into the one fat
location so we can ask to by-pass 'services' if we don't need them.
See JIRA for an example hbase-server.xml that has config to shutdown
WAL, cache, etc.
Adds checks if a service/thread has been setup before going to use it.
Renames the ExecutorService in HRegionServer from service to
executorService.
See JIRA too for example Connection implementation that makes use of
Connection plugin point to receive a replication stream. The default
replication sink catches the incoming replication stream, undoes the
WALEdits and then creates a Table to call a batch with the
edits; up on JIRA, an example Connection plugin (legit, supported)
returns a Table with an overridden batch method where in we do index
inserts returning appropriate results to keep the replication engine
ticking over.
Upsides: an unadulterated RegionServer that will keep replication metrics
and even hosts a web UI if wanted. No hacks. Just ordained configs
shutting down unused services. Injection of the indexing function at a
blessed point with no pollution by hbase internals; only public imports.
No user of Private nor LimitedPrivate classes.
A hack to "hide" the protobufs, but it's not going to be a trivial
change to remove use of protobufs entirely as they're serialized
into the hbase:quota table.
* Change imports from org.codehaus to com.fasterxml
* Exclude transitive jackson1 from hadoop and others
* Minor test cleanup to add assert messages, fix some parameter order
* Add anti-pattern check for using jackson 1 imports
* Add explicit non-null serialization directive to ScannerModel
Purges Server, MasterServices, and RegionServerServices from
CoprocessorEnvironments. Replaces removed functionality with
a set of carefully curated methods on the *CoprocessorEnvironment
implementations (Varies by CoprocessorEnvironment in that the
MasterCoprocessorEnvironment has Master-type facility exposed,
and so on).
A few core Coprocessors that should long ago have been converted
to be integral, violate their context; e.g. a RegionCoprocessor
wants free access to a hosting RegionServer (which may or may not
be present). Rather than let these violators make us corrupte the
CP API, instead, we've made up a hacky system that allows core
Coprocessors access to internals. A new CoreCoprocessor Annotation
has been introduced. When loading Coprocessors, if the instance is
annotated CoreCoprocessor, we pass it an Environment that has been
padded w/ extra-stuff. On invocation, CoreCoprocessors know how to
route their way to these extras in their environment.
See the *CoprocessoHost for how the do the check for CoreCoprocessor
and pass a fatter *Coprocessor, one that allows getting of either
a RegionServerService or MasterService out of the environment
via Marker Interfaces.

No need to go via RSS to getOnlineTables; just use HRS.

- Table moving to RSG was buggy, because it left the table unassigned.
Now it is fixed we immediately assign to an appropriate RS
(MoveRegionProcedure).
- Table was locked while moving, but unassign operation hung, because
locked table queues are not scheduled while locked. Fixed.
- ProcedureSyncWait was buggy, because it searched the procId in
executor, but executor does not store the return values of internal
operations (they are stored, but immediately removed by the cleaner).
- list_rsgroups in the shell show also the assigned tables and servers.

- Change Service Coprocessor#getService() to List<Service> Coprocessor#getServices()
- Checkin the finalized design doc into repo
- Added example to javadoc of Coprocessor base interface on how to implement one in the new design
------------------------------------------------------
TL;DR
------------------------------------------------------
We are moving from Inheritence
- Observer *is* Coprocessor
- FooService *is* CoprocessorService
To Composition
- Coprocessor *has* Observer
- Coprocessor *has* Service
------------------------------------------------------
Design Changes
------------------------------------------------------
- Adds four new interfaces - MasterCoprocessor, RegionCoprocessor, RegionServierCoprocessor,
WALCoprocessor
- These new *Coprocessor interfaces have a get*Observer() function for each observer type
supported by them.
- Added Coprocessor#getService() to base interface. All extending *Coprocessor interfaces will
get it from the base interface.
- Added BulkLoadObserver hooks to RegionCoprocessorHost instad of SecureBulkLoadManager doing its
own trickery.
- CoprocessorHost#find*() fuctions: Too many testing hooks digging into CP internals.
Deleted if can, else marked @VisibleForTesting.
------------------------------------------------------
Backward Compatibility
------------------------------------------------------
- Old coprocessors implementing *Observer won't get loaded (no backward compatibility guarantees).
- Third party coprocessors only implementing Coprocessor will not get loaded (just like Observers).
- Old coprocessors implementing CoprocessorService (for master/region host)
/SingletonCoprocessorService (for RegionServer host) will continue to work with 2.0.
- Added test to ensure backward compatibility of CoprocessorService/SingletonCoprocessorService
- Note that if a coprocessor implements both observer and service in same class, its service
component will continue to work but it's observer component won't work.
------------------------------------------------------
Notes
------------------------------------------------------
Did a side-by-side comparison of CPs in master and after patch. These coprocessors which were just
CoprocessorService earlier, needed a home in some coprocessor in new design. For most it was clear
since they were using a particular type of environment. Some were tricky.
- JMXListener - MasterCoprocessor and RSCoprocessor (because jmx listener makes sense for
processes?)
- RSGroupAdminEndpoint --> MasterCP
- VisibilityController -> MasterCP and RegionCP
These were converted to RegionCoprocessor because they were using RegionCoprocessorEnvironment
which can only come from a RegionCPHost.
- AggregateImplementation
- BaseRowProcessorEndpoint
- BulkDeleteEndpoint
- Export
- RefreshHFilesEndpoint
- RowCountEndpoint
- MultiRowMutationEndpoint

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.

- Moves out o.a.h.h.{mapred, mapreduce} to new hbase-mapreduce module which depends
on hbase-server because of classes like *Snapshot{Input,Output}Format.java, WALs, replication, etc
- hbase-backup depends on it for WALPlayer and MR job stuff
- A bunch of tools needed to be pulled into hbase-mapreduce becuase of their dependencies on MR.
These are: CompactionTool, LoadTestTool, PerformanceEvaluation, ExportSnapshot
This is better place of them than hbase-server. But ideal place would be in separate hbase-tools module.
- There were some tests in hbase-server which were digging into these tools for static util funtions or
confs. Moved these to better/easily shared place. For eg. security related stuff to HBaseKerberosUtils.
- Note that hbase-mapreduce has secondPartExecution tests. On my machine they took like 20 min, so maybe
more on apache jenkins. That's basically equal reduction of runtime of hbase-server tests, which is a
big win!

Breaking change to our ReplicationEndpoint and BaseReplicationEndpoint.
ReplicationEndpoint implemented Guava 0.12 Service. An abstract
subclass, BaseReplicationEndpoint, provided default implementations
and facility, among other things, by extending Guava
AbstractService class.
Both of these HBase classes were marked LimitedPrivate for
REPLICATION so these classes were semi-public and made it so
Guava 0.12 was part of our API.
Having Guava in our API was a mistake. It anchors us and the
implementation of the Interface to Guava 0.12. This is untenable
given Guava changes and that the Service Interface in particular
has had extensive revamp and improvement done. We can't hold to
the Guava Interface. It changed. We can't stay on Guava 0.12;
implementors and others on our CLASSPATH won't abide being stuck
on an old Guava.
So this class makes breaking changes. The unhitching of our Interface
from Guava could only be done in a breaking manner. It undoes the
LimitedPrivate on BaseReplicationEndpoint while keeping it for the RE
Interface. It means consumers will have to copy/paste the
AbstractService-based BRE into their own codebase also supplying their
own Guava; HBase no longer 'supplies' this (our Guava usage has
been internalized, relocated).
This patch then adds into RE the basic methods RE needs of the old
Guava Service rather than return a Service to start/stop only to go
back to the RE instance to do actual work. A few method names had to
be changed so could make implementations with Guava Service internally
and not have RE method names and types clash). Semantics remained the
same otherwise. For example startAsync and stopAsync in Guava are start
and stop in RE.
* Fixed ServerCrashProcedure to set forceNewPlan to false for instances AssignProcedure. This enables balancer to find most suitable target server

Instead of using an Atomic Reference to data and aborting when we detect
that new data comes in, use the native cancellation/pre-emption features
of Java Future.
Behavior prior to these changes is to call expireServer(), log exception and suppress it. These changes will result in RS receiving the YouAreDeadException and treating it as a fatal error. This 'fail fast' approach will help us stabilize the code. This behavior can be reconsidered later if necessary.

HBASE-17748 Include HBase snapshots in space quotas
Introduces a new Chore in the Master which computes the size

Includes some test stabilization, trying to make the tests more
