JMXCacheBuster resets the metrics state at various points in time. These
events can potentially race with a master shutdown. When the master is
tearing down, metrics initialization can touch a lot of unsafe state,
for example invalidated FS objects. To avoid this, this patch makes
the getMetrics() a no-op when the master is either stopped or in the
process of shutting down. Additionally, getClusterId() when the server
is shutting down is made a no-op.
Simulating a test for this is a bit tricky but with the patch I don't
locally see the long stacktraces from the jira.

(cherry picked from commit 6f213e9d5a)
Includes the following, incorporating HBASE-20439 and HBASE-20440, too.
1)
HBASE-18133 Decrease quota reaction latency by HBase
Certain operations in HBase are known to directly affect
the utilization of tables on HDFS. When these actions
occur, we can circumvent the normal path and notify the
Master directly. This results in a much faster response to
changes in HDFS usage.
This requires FS scanning by the RS to be decoupled from
the reporting of sizes to the Master. An API inside each
RS is made so that any operation can hook into this call
in the face of other operations (e.g. compaction, flush,
bulk load).
2)
HBASE-18135 Implement mechanism for RegionServers to report file archival for space quotas
This de-couples the snapshot size calculation from the
SpaceQuotaObserverChore into another API which both the periodically
invoked Master chore and the Master service endpoint can invoke. This
allows for multiple sources of snapshot size to reported (from the
multiple sources we have in HBase).
When a file is archived, snapshot sizes can be more quickly realized and
the Master can still perform periodical computations of the total
snapshot size to account for any delayed/missing/lost file archival RPCs.
3)
HBASE-20531 RS may throw NPE when close meta regions in shutdown procedure.
Introducing property hbase.regionserver.user.metrics.enabled(Default:true)
to disable user metrics in case it accounts for any performance issues

* modify the jar checking script to take args; make hadoop stuff optional
* separate out checking the artifacts that have hadoop vs those that don't.
* * Unfortunately means we need two modules for checking things
* * put in a safety check that the support script for checking jar contents is maintained in both modules
* * have to carve out an exception for o.a.hadoop.metrics2. :(
* fix duplicated class warning
* clean up dependencies in hbase-server and some modules that depend on it.
* allow Hadoop to have its own htrace where it needs it
* add a precommit check to make sure we're not using old htrace imports

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.

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.

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)

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.
Contains the following commits:
HBASE-17748 Include HBase snapshots in space quotas
Introduces a new Chore in the Master which computes the size
of the snapshots included in a cluster. The size of these
snapshots are included in the table's which the snapshot was created
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
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
Following AMv2 procedures are modified to override onSubmit(), onFinish() hooks provided by HBASE-17888 to do
metrics calculations when procedures are submitted and finshed:
* AssignProcedure
* UnassignProcedure
* MergeTableRegionProcedure
* SplitTableRegionProcedure
* ServerCrashProcedure
Following metrics is collected for each of the above procedure during lifetime of a process:
* Total number of requests submitted for a type of procedure
* Histogram of runtime in milliseconds for successfully completed procedures
* Total number of failed procedures
As we are moving away from Hadoop's metric2, hbase-metrics-api module is used for newly added metrics.
Modified existing tests to verify count of procedures.
