Sean Busbey 9927c2e14a HBASE-20070 refactor website generation
* 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.

Balazs Meszaros 992b5d8630 HBASE-10092 Move up on to log4j2
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.

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.

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.

Apekshit Sharma 59d034106f HBASE-18640 Move mapreduce out of hbase-server into separate module.
- Moves out o.a.h.h.{mapred, mapreduce} to new hbase-mapreduce module which depends
  on hbase-server because of classes like *Snapshot{Input,Output}Format.java, WALs, replication, etc
- hbase-backup depends on it for WALPlayer and MR job stuff
- A bunch of tools needed to be pulled into hbase-mapreduce becuase of their dependencies on MR.
  These are: CompactionTool, LoadTestTool, PerformanceEvaluation, ExportSnapshot
  This is better place of them than hbase-server. But ideal place would be in separate hbase-tools module.
- There were some tests in hbase-server which were digging into these tools for static util funtions or
  confs. Moved these to better/easily shared place. For eg. security related stuff to HBaseKerberosUtils.
- Note that hbase-mapreduce has secondPartExecution tests. On my machine they took like 20 min, so maybe
  more on apache jenkins. That's basically equal reduction of runtime of hbase-server tests, which is a
  big win!

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

stack 95c1dc93fb HBASE-15638 Shade protobuf
Which includes

    HBASE-16742 Add chapter for devs on how we do protobufs going forward

    HBASE-16741 Amend the generate protobufs out-of-band build step
    to include shade, pulling in protobuf source and a hook for patching protobuf

    Removed ByteStringer from hbase-protocol-shaded. Use the protobuf-3.1.0
    trick directly instead. Makes stuff cleaner. All under 'shaded' dir is
    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 hbase-client/src/main/java/org/apache/hadoop/hbase/client/AbstractRegionServerCallable
            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.

Josh Elser 72855c584e HBASE-13236 Add addt'l lifecycle-mapping executions.
Adds a number of lifecycle-mapping entries which
prevent errors from showing up in Eclipse on a fresh
import of HBase. For plugins defined in the top-level
pom, the mapping is added there; otherwise, the mapping
is pushed down to the child pom.
