Make the #copyCellInto method smaller so it inlines; we do it by
checking for the common type early and then taking a code path
that presumes ByteBufferExtendedCell -- avoids checks.
- -jar parameter now accepts multiple jar files and directories of jar files.
- observer classes can be verified by -class option.
- -table parameter was added to check table level coprocessors.
- -config parameter was added to obtain the coprocessor classes from
HBase cofiguration.
- -scan option was removed.

With prefetch-on-open enabled, the task doing the prefetching was using
non-positional (i.e. streaming) reads. If the main (non-prefetch) thread
was also using non-positional reads, these two would conflict, because
inputstreams are not thread-safe for non-positional reads.
In the case of an encrypted filesystem, this could cause JVM crashes,
etc, as underlying cipher buffers were freed underneath the racing
threads. In the case of a non-encrypted filesystem, less severe errors
would be thrown. The included unit test reproduces the latter case.

Also changes modify table operations to help the case where a MTP spans
two master, avoiding the sanity-checks propagating back to the client
unnecessarily.

ModifyTableProcedure is using MoveRegionProcedure in a way
that was unintended from the original implementation. As such,
we have to guard against certain usages of it. We know we can
re-open OPEN regions, but regions in OPENING will similarly
soon be OPEN (thus, we want to reopen those regions too).

* 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

A reattempt at fixing HBASE-20173 [AMv2] DisableTableProcedure concurrent to ServerCrashProcedure can deadlock
The scenario is a SCP after processing WALs, goes to assign regions that
were on the crashed server but a concurrent Procedure gets in there
first and tries to unassign a region that was on the crashed server
(could be part of a move procedure or a disable table, etc.). The
unassign happens to run AFTER SCP has released all RPCs that
were going against the crashed server. The unassign fails because the
server is crashed. The unassign used to suspend itself only it would
never be woken up because the server it was going against had already
been processed. Worse, the SCP could not make progress because the
unassign was suspended with the lock on a region that it wanted to
assign held making it so it could make no progress.
In here, we add to the unassign recognition of the state where it is
running post SCP cleanup of RPCs. If present, unassign moves to finish
instead of suspending itself.
Includes a nice unit test made by Duo Zhang that reproduces nicely the
hung scenario.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/FailedRemoteDispatchException.java
Moved this class back to hbase-procedure where it belongs.

M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/NoServerDispatchException.java
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/NullTargetServerDispatchException.java
Specializiations on FRDE so we can be more particular when we say there
was a problem.
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/RemoteProcedureDispatcher.java
Change addOperationToNode so we throw exceptions that give more detail
on issue rather than a mysterious true/false
M hbase-protocol-shaded/src/main/protobuf/MasterProcedure.proto
Undo SERVER_CRASH_HANDLE_RIT2. Bad idea (from HBASE-20173)
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/ServerManager.java
Have expireServer return true if it actually queued an expiration. Used
later in this patch.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Hide methods that shouldn't be public. Add a particular check used out
in unassign procedure failure processing.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/MoveRegionProcedure.java
Check that server we're to move from is actually online (might
catch a few silly move requests early).
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStates.java
Add doc on ServerState. Wasn't being used really. Now we actually stamp
a Server OFFLINE after its WAL has been split. Means its safe to assign
since all WALs have been processed. Add methods to update SPLITTING
and to set it to OFFLINE after splitting done.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
Change logging to be new-style and less repetitive of info.
Cater to new way in which .addOperationToNode returns info (exceptions
rather than true/false).
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/UnassignProcedure.java
Add looking for the case where we failed assign AND we should not
suspend because we will never be woken up because SCP is beyond
doing this for all stuck RPCs.
Some cleanup of the failure processing grouping where we can proceed.
TODOs have been handled in this refactor including the TODO that
wonders if it possible that there are concurrent fails coming in
(Yes).
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/ServerCrashProcedure.java
Doc and removing the old HBASE-20173 'fix'.
Also updating ServerStateNode post WAL splitting so it gets marked
OFFLINE.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestServerCrashProcedureStuck.java
Nice test by Duo Zhang.
