Add switching on/off of compactions.
Switching off compactions will also interrupt any currently ongoing compactions.
Adds a "compaction_switch" to hbase shell. Switching off compactions will
interrupt any currently ongoing compactions. State set from shell will be
lost on restart. To persist the changes across region servers modify
hbase.regionserver.compaction.enabled in hbase-site.xml and restart.

- 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.

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
Refactoring in here is minor. A few methods that used support bypass
no longer do so removed the check and the need of an if/else meant a
left-shift in some code.

Ditto

* Change imports from org.codehaus to com.fasterxml

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.

Signed-off-by: Chia-Ping Tsai <chia7712@gmail.com>
- 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
- SecureBulkLoadEndpoint
- TokenProvider

This is based on patch sent me by Balazs Meszaros. The good stuff in

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

- 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:

from HDFS usage.
Includes some test stabilization, trying to make the tests more
deterministic by ensuring we observe stable values as we know
that those values are mutable. This should help avoid problems
where size reports are delayed and we see an incomplete value.
HBASE-17752 Shell command to list snapshot sizes WRT quotas
HBASE-17840 Update hbase book to space quotas on snapshots
Other changes:
- Update corresponding tests in TestAdmin2. Removed tests centered around serverName part of old functions.
- Remove dead functions from ProtobufUtil and ServerManager
- Rename closeRegion* functions in HBTU to unassignRegion*

Selective add of dependency on hbase-thirdparty jars.
Update to READMEs on how protobuf is done (and update to refguide).
Removed all checked in generated protobuf files. They are generated
on the fly now as part of mainline build.
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
hbase-thirdparty jars. Update to READMEs on how protobuf is done (and update to
refguide) Removed all checked in generated protobuf files. They are generatedon

Revert "Revert "HBASE-18266 Create static empty byte array to save memory (Ben Epstein)""
... i.e. a reapply but with correct JIRA this time.
This reverts commit 3a0db474a2.
This issue adds comments and a sort so system tables are queued first
(which will ensure they go out first). This should be good enough
along w/ existing scheduling mechanisms to ensure system/meta get
assigned first.

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.
* Implement the RegionServer reading violation from the quota table
* Implement the Master reporting violations to the quota table
* RegionServers need to track its enforced policies
Adds a new Chore to the Master that analyzes the reports that are
sent by RegionServers. The Master must then, for all tables with
quotas, determine the tables that are violating quotas and move
those tables into violation. Similarly, tables no longer violating
the quota can be moved out of violation.
The Chore is the "stateful" bit, managing which tables are and
are not in violation. Everything else is just performing
computation and informing the Chore on the updated state.
Added InterfaceAudience annotations and clean up the QuotaObserverChore
constructor. Cleaned up some javadoc and QuotaObserverChore. Reuse
the QuotaViolationStore impl objects.
- internalRestoreSnapshot() returns future which completes by just getting proc_id from master. Changed it to wait for the procedure to complete.
- Refactor TestAsyncSnapshotAdminApi: Add cleanup() which deletes all tables and snapshots after every test run. Simplifies individual tests.

The special "auth" ZK ACL scheme will always set the ACL's id (the
user who is allowed) to be the authenticated user of the ZK connection.
This results in the HBase superuser not actually receiving the
permissions as the ZKUtil intends to do. Since we know we have security
enabled, we can instead explicitly list "sasl" as the ACL scheme
instead.
Reason for refactor:
In cases where one might need to use multiple observers, say region, master and regionserver; and the fact that only one class can be extended, it gives rise to following pattern:
public class BaseMasterAndRegionObserver
extends BaseRegionObserver
implements MasterObserver
class AccessController
extends BaseMasterAndRegionObserver
implements RegionServerObserver
were BaseMasterAndRegionObserver is full copy of BaseMasterObserver.
There is an example of simple case too where the current design fails.
Say only one observer is needed by the coprocessor, but the design doesn't permit extending even that single observer (see RSGroupAdminEndpoint), that leads to copy of full Bas
e...Observer class into coprocessor class leading to 1000s of lines of code and this ugly mix of 5 main functions with 100 useless functions.
Javadocs changes:
- Adds class comments on 'default' methods and expectations.
- Adds explanaiton of Exception handling in Observers' class comment. Removes redundant @throws before each function.
- Improves javadocs for a bunch of functions
- deletes empty @params in a bunch of places

Addresses review comments by Sean Busbey and Appy that happened
to come in long after the commit of HBASE-6721, the original
rsgroup issue.
Also includes subsequent accommodation of Duo Zhang review.
Adds a new type to hold hostname and port. It is called
Address. It is a facade over Guava's HostAndPort. Replace
all instances of HostAndPort with Address. In particular,
those places where HostAndPort was part of the rsgroup
public API.
Fix licenses. Add audience annotations.
Cleanup and note concurrency expectation on a few core classes.
In particular, all access on RSGroupInfoManager is made
synchronized.
M hbase-client/src/main/java/org/apache/hadoop/hbase/ServerName.java
Host the hostname and port in an instance of the new type Address.
