------------------------------------------------------
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
- SecureBulkLoadEndpoint
- TokenProvider

This is based on patch sent me by Balazs Meszaros. The good stuff in
here is from him. This patch does less than his ambition. It changes
Admin class only. Can work on making AsyncAdmin cohere in a follow-on.
* Deprecates getAlterStatus. Everywhere else we talk of 'modify' rather
'alter' and should use Future returned from async instead.
* isTableAvailable(TableName, byte [][]) has been deprecated to be
removed; use the overrie instead. This is a weird method.
* Changed listTableDescriptor to getDescriptor.
* Renamed other like methods to have same pattern (deprecating the old):
balancer => balance
setBalancerRunning => balancerSwitch
setNormalizerRunning => normalizerSwitch
enableCatalogJanitor => catalogJanitorSwitch
setCleanerChoreRunning => cleanerChoreSwitch
setSplitOrMergeEnabled => splitOrMergeEnabledSwitch
* Renamed (with deprecation of old) runCatalogScan => runCatalogJanitor.
* Reviewed generated javadoc and made some edits; purged reference to
hbase issues from our API, fixed param names, etc.
* Made all the enable services methods have same pattern.
* Renamed takeSnapshotAsync as snapshotAsync (with deprecation of old)
* Renamed execProcedureWithRet as execProcedureWithReturn (with
deprecation)

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.. ] }

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.
Move Driver to be the main-class in hbase-mapreduce jar rather than
in the hbase-server jar.
Reference the hbase-server and shaded protobuf so they get bundled
when you do 'hbase mapredcp'.
classpath issue when running as a developer fixed
removed thrift webapp from server (it's not used at all, since moved to thrift webapp)

- 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
* Fixed and enabled TestRestartCluster#testRetainAssignmentOnRestart on master

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.

Changes the configuration hbase.balancer.tablesOnMaster from list of
table names to instead be a boolean; true if master carries
tables/regions and false if it does not.
Adds a new configuration hbase.balancer.tablesOnMaster.systemTablesOnly.
If true, hbase.balancer.tablesOnMaster is considered true but only
system tables are put on the master.
