* HBASE-23257: Track clusterID in stand by masters (#798)
This patch implements a simple cache that all the masters
can lookup to serve cluster ID to clients. Active HMaster
is still responsible for creating it but all the masters
will read it from fs to serve clients.
RPCs exposing it will come in a separate patch as a part of
HBASE-18095.

* HBASE-23275: Track active master's address in ActiveMasterManager (#812)
Currently we just track whether an active master exists.
It helps to also track the address of the active master in
all the masters to help serve the client RPC requests to
know which master is active.

* HBASE-23281: Track meta region locations in masters (#830)
* HBASE-23281: Track meta region changes on masters
This patch adds a simple cache that tracks the meta region replica
locations. It keeps an eye on the region movements so that the
cached locations are not stale.
This information is used for servicing client RPCs for connections
that use master based registry (HBASE-18095). The RPC end points
will be added in a separate patch.

* HBASE-23304: RPCs needed for client meta information lookup
This patch implements the RPCs needed for the meta information
lookup during connection init. New tests added to cover the RPC
code paths. HBASE-23305 builds on this to implement the client
side logic.
Fixed a bunch of checkstyle nits around the places the patch
touches.

Make hbase:meta region schema dynamic.

Get hbase:meta schema from filesystem rather than from hard-coding.
Make it so hbase:meta can be altered. TableState for hbase:meta
was hardcoded ENABLED. Make it dynamic. State is now kept in
current active Master. It is transient so falls back to default
if Master crashes. Add to registry a getMetaTableState
which reads mirrored state from zookeeper (NOT from Master and
defaults ENABLED if no implementation or error fetching state).
hbase:meta schema will be bootstrapped from the filesystem.
Changes to filesystem schema are atomic so we should be ok if
Master fails mid-edit (TBD). Undoes a bunch of guards that
prevented our being able to edit hbase:meta.
TODO: Tests, more clarity around hbase:meta table state, and undoing
references to hard-coded hbase:meta regioninfo.

This will give the Master's TableStateManager's opinion rather than

If we try to delete too many znodes at once, we'll smack into the
jute.maxbuffer size. Try to prevent that from happening. The dominating

HBASE-22059 amendment and subsequent ammendments to HBASE-22052.
See HBASE-22052 for full story.
jersey-core is problematic. It was transitively included from hadoop
and polluting our CLASSPATH with an implementation of a 1.x version
of the javax.ws.rs.core.Response Interface from jsr311-api when we
want the javax.ws.rs-api 2.x version.

Remove redundant version specification (and the odd property define
done already up in parent pom).

M pom.xml
Add jersey-core exclusions to all dependencies that pull it in
except hadoop-minicluster. mr tests fail w/o the jersey-core
so let it in for minicluster and then in modules, exclude it
where it causes damage as in hbase-it.
Instead of being an ephemeral state set by hbck, maintenance mode is now
an explicit toggle set by either configuration property or environment
variable. In maintenance mode, master will host system tables and not
assign any user-space tables to RSs. This gives operators the ability to
affect repairs to meta table with fewer moving parts.
Recent versions of ZooKeeper whitelist the so-called 4-letter word admin
commands, and 'stat' is not in the default whitelist. Set system property
zookeeper.4lw.commands.whitelist=* in MiniZooKeeperCluster#setupTestEnv
as we do not need to whitelist 4-letter commands for unit tests.
* 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.

When we run MapReduce jobs via `yarn jar`, the special classloader
which is set up by YARN creates a situation where our invocation of
package-private Hadoop classes throws an IllegalAccessError. It's
easiest to just remove these and rethink how to avoid further
Hadoop metrics2 issues.

First, we add test resources to CLASSPATH when tests run. W/o it, there
was no logging of hbase-zookeeper test output (not sure why I have to
add this here and not over in hbase-server; research turns up nothing
so far).

Wait until ZK is connected before progressing. On my slow zk, it could
be a while post construction before zk connected. Using an unconnected

Change session timeout to default 30s from 1s which was way too short.
M hbase-zookeeper/src/test/resources/log4j.properties
Set zk logs to DEBUG level in this module at least.
Adds a ZooKeeperHelper class that has utility to help interacting w/ ZK.
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.

- 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)

- 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)
