(Forward port from branch-2; simplified by the fact that there
is no hadoop-2.0 profile on master branch)
Make it so our published poms carry the minimum needed to run
an hbase; the published pom has no profiles -- the profiles
specified at build time are resolved, their dependencies inlined,
and then they are stripped -- and no build-time, or plugins
dependencies or properties, etc. Resultant poms have explicit
hadoop lib versions baked in -- no more being able to choose
hbase with hadoop2 or haddop3 at downstream build time by setting
a '-Dhadoop.profile=X.0'.
Pattern is to add profiles when none in sub-modules when
the flatten plugin complains it can't resolve an hadoop
dependency's 'version' (e.g. hadoop-common, hadoop-hdfs).
Adding the profile in the sub-module make it so the flatten
plugin can figure 'hadoop.version' definitively.
(In master there is only the hadoop-3.0 profile).
Another spin on the above happens when profiles already exist
in submodule but the flatten plugin is complaining it can't
figure figure version on an hadoop dependency NOT under
profiles. Below, we move the delinquent hadoop dependency under
existing profiles (minikdc was the usual dependency outside
profiles in sub-modules that flatten complained about).
Sometimes, moving an hadoop dependency under a profile, there
would be excludes on the local dependency. If the parent pom
excludes section was missing the local excludes, we added them
up to the parent module so all excluding is done up there in
the parent profile dependencyManagement section.

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.

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.
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
the fly now as part of mainline build.
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.

now generated.
HBASE-16567 Upgrade to protobuf-3.1.x
Regenerate all protos in this module with protoc3.
Redo ByteStringer to use new pb3.1.0 unsafebytesutil
instead of HBaseZeroCopyByteString
HBASE-16264 Figure how to deal with endpoints and shaded pb Shade our protobufs.
Do it in a manner that makes it so we can still have in our API references to
com.google.protobuf (and in REST). The c.g.p in API is for Coprocessor Endpoints (CPEP)
This patch is Tactic #4 from Shading Doc attached to the referenced issue.
Figuring an appoach took a while because we have Coprocessor Endpoints
mixed in with the core of HBase that are tough to untangle (FIX).
Tactic #4 (the fourth attempt at addressing this issue) is COPY all but
the CPEP .proto files currently in hbase-protocol to a new module named
hbase-protocol-shaded. Generate .protos again in the new location and
then relocate/shade the generated files. Let CPEPs keep on with the
old references at com.google.protobuf.* and
org.apache.hadoop.hbase.protobuf.* but change the hbase core so all
instead refer to the relocated files in their new location at
org.apache.hadoop.hbase.shaded.com.google.protobuf.*.
Let the new module also shade protobufs themselves and change hbase
core to pick up this shaded protobuf rather than directly reference
com.google.protobuf.
This approach allows us to explicitly refer to either the shaded or
non-shaded version of a protobuf class in any particular context (though
usually context dictates one or the other). Core runs on shaded protobuf.
CPEPs continue to use whatever is on the classpath with
com.google.protobuf.* which is pb2.5.0 for the near future at least.
See above cited doc for follow-ons and downsides. In short, IDEs will complain
about not being able to find the shaded protobufs since shading happens at package
time; will fix by checking in all generated classes and relocated protobuf in
a follow-on. Also, CPEPs currently suffer an extra-copy as marshalled from
non-shaded to shaded. To fix. Finally, our .protos are duplicated; once
shaded, and once not. Pain, but how else to reveal our protos to CPEPs or
C++ client that wants to talk with HBase AND shade protobuf.
Details:
Add a new hbase-protocol-shaded module. It is a copy of hbase-protocol
i with all relocated offset from o.a.h.h. to o.a.h.h.shaded. The new module
also includes the relocated pb. It does not include CPEPs. They stay in
their old location.
Add another module hbase-endpoint which has in it all the endpoints
that ship as part of hbase -- at least the ones that are not
entangled with core such as AccessControl and Auth. Move all protos
for these CPEPs here as well as their unit tests (mostly moving a
bunch of stuff out of hbase-server module)
Much of the change looks like this:
-import org.apache.hadoop.hbase.protobuf.ProtobufUtil;
-import org.apache.hadoop.hbase.protobuf.generated.ClusterIdProtos;
+import org.apache.hadoop.hbase.protobuf.shaded.ProtobufUtil;
+import org.apache.hadoop.hbase.shaded.protobuf.generated.ClusterIdProtos;
In HTable and in HBaseAdmin, regularize the way Callables are used and also hide
protobuf usage as much as possible moving it up into Callable super classes or out
to utility classes. Still TODO is adding in of retries, etc., but can wait on
procedure which will redo all this.
Also in HTable and HBaseAdmin as well as in HRegionServer and Server, be explicit
when using non-shaded protobuf. Do the full-path so it is clear. This is around
endpoint coprocessors registration of services and execution of CPEP methods.
Shrunk ProtobufUtil by moving methods used by one CPEP only back to the CPEP either
into Client class or as new Util class; e.g. AccessControlUtil.
There are actually two versions of ProtobufUtil now; a shaded one and a subset
that is used by CPEPs doing non-shaded work.
Made it so hbase-common no longer depends on hbase-protocol (with Matteo's help)
R*Converter classes got moved down under shaded package -- they are for internal
use only. There are no non-shaded versions of these classes.

D RetryingCallableBase
Not used anymore and we have too many tiers of Callables so removed/cleaned-up.
A ClientServicecallable
Had to add this one. RegionServerCallable was made generic so it could be used
for a few Interfaces (Client and Admin). Then added ClientServiceCallable to
implement RegionServerCallable with the Client Interface.
* corrects license/notice for source distribution

* uses append-resources to include supplemental info on jars with 3rd party works in source
* adds an hbase specific resource bundle for jars that include 3rd party works for binaries
** uses supplemental-model to fill in license gaps
** uses the above and a shade plugin transformation to build proper files for shaded jars.
** uses the above and the assembly plugin to build the proper files for bin assembly
* adds a NOTICE item for things copied out of Hadoop (TODO legal-discuss)
