For a egionserver's view of a table (the regions
that belong to a table hosted on a regionserver),
this change tracks the latencies of operations that
affect the regions for this table.
Tracking at the per-table level avoids the memory bloat
and performance impact that accompanied the previous
per-region latency metrics while still providing important
details for operators to consume.

- 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.
- Other minor improvements
It seems like the original reason this execution filter was added is no
longer an issue for 2.0. Actually, these entries actually preclude
Eclipse from correctly using the Java8 source/target version that we
have specified (which creates numerous compilation errors in Eclipse)

Update timeouts for TestRegionObserverInterface.
Reason: There are ~10 tests there, each with 5 min individual timeout. Too much. The test class is labelled MediumTests,
let's used that with our standard CategoryBasedTimeout. 3 min per test function should be enough even on slower Apache machines.
This avoids the situation where the build machine has sufficient disk
space (a few GB's at most) to run an HBase test, but the default YARN
configuration would preclude the NM's from starting correctly. This
should eliminate a trivial source of build flakiness based on the host
machines being used.

Removed TestHRegion#testMemstoreSizeWithFlushCanceling test.
CPs are not able to cancel a flush any more so this test was
failing; removed it (It was testing memory accounting kept
working across a cancelled flush).

Use header and footer in our *.jsp pages to avoid unnecessary redundancy (copy-paste of code)
Misc edits:
- Due to redundancy, new additions make it to some places but not others. For eg there are missing links to "/logLevel", "/processRS.jsp" in few places.
- Fix processMaster.jsp wrongly pointing to rs-status instead of master-status (probably due to copy paste from processRS.jsp)
- Deleted a bunch of extraneous "</a>" in processMaster.jsp & processRS.jsp
- Added missing </div> tag in snapshot.jsp
- Deleted fossils of html5shiv.js. It's uses and the js itself were deleted in the commit "819aed4ccd073d818bfef5931ec8d248bfae5f1f"
- Fixed wrongly matched heading tags
- Deleted some unused variables
Tested:
Ran standalone cluster and opened each page to make sure it looked right.
Sidenote:
Looks like HBASE-3835 started the work of converting from jsp to jamon, but the work didn't finish. Now we have a mix of jsp and jamon. Needs reconciling, but later.
- Moved DrainingServerTracker and RegionServerTracker to hbase-server:o.a.h.h.master.
- Moved SplitOrMergeTracker to oahh.master (because it depends on a PB)
- Moving hbase-client:oahh.zookeeper.* to hbase-zookeeper module. After HBASE-19200, hbase-client doesn't need them anymore (except 3 classes).
- Renamed some classes to use a consistent naming for classes - ZK instead of mix of ZK, Zk , ZooKeeper. Couldn't rename following public classes: MiniZooKeeperCluster, ZooKeeperConnectionException. Left RecoverableZooKeeper for lack of better name. (suggestions?)
- Sadly, can't move tests out because they depend on HBaseTestingUtility (which defeats part of the purpose - trimming down hbase-server tests. We need to promote more use of mocks in our tests)
Remove a few unused imports.
Remove TestAsyncRegionAdminApi#testOffline, a test for a condition that
no longer exists (no offlining supported in hbase2).

There is no functionality change except for below:
* Variable lastIndexExclusive was getting incremented while locking rows corresponding to input
operations. As a result when getRowLockInternal() method throws TimeoutIOException only operations
in range [nextIndexToProcess, lastIndexExclusive) was getting marked as FAILED before raising
exception up the call stack. With these changes all operations are getting marked as FAILED.
* Cluster Ids of first mutation is used consistently for entire batch. Previous behavior was to use
cluster ids of first mutation in a mini-batch

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.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/RSRpcServices.java
Ditto
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/RegionCoprocessorHost.java
In here label explicitly those methods that are bypassable.
Some changes to make sure we call the corresponding execOperation.
TestMasterObserver had a bunch of test of bypass method. All removed or
disabled.

Added filterCell method to Filter, it calls filterKeyValue by default
Deprecated filterKeyValue in Filter, bud added default functionality to return Filter.ReturnCode.INCLUDE.
Added filterKeyValue (calling filterCell) to Filters extending FilterBase to be backward compatible.
renamed filterKeyValue to filterCell in all implementations
changed all internal calls to use filterCell instead of filterKeyValue
changed tests too
This way the change is simple and backward compatible.
Any existing custom filter should work since they override filterKeyValue
and the implementation is called by Filter.filterCell.
Moved FilterWrapper to hbase-server

- int getReadRpcTimeout()
- int getWriteRpcTimeout()
- int getOperationTimeout()
Add the following methods to Table:
- long getRpcTimeout(TimeUnit)
- long getReadRpcTimeout(TimeUnit)
- long getWriteRpcTimeout(TimeUnit)
- long getOperationTimeout(TimeUnit)

Change name of Interface OnlineRegions to MutableOnlineRegions.
Change name of Interface ImmutableOnlineRegions to OnlineRegions.
Did this since OnlineRegions is for consumer other than internals.
Add a getOnlineRegions to the RegionCoprocessorEnvironment and to
RegionServerCoprocessorEnvironment so CPs can 'access' local
Regions directly.
- 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.

M hbase-endpoint/src/main/java/org/apache/hadoop/hbase/security/access/SecureBulkLoadEndpoint.java

Added doc on where it is used and added back a few methods we'd
removed.
A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/CoreCoprocessor.java

We no longer have access to MasterServices. Don't need it actually.
Use short-circuiting Admin instead.
D hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CoprocessorRegionServerServices.java
Removed. Not needed now we do CP Env differently.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
No need to go via RSS to getOnlineTables; just use HRS.
And so on. Adds tests to ensure we can only get at extra info
if the CP has been properly marked.
