The special "auth" ZK ACL scheme will always set the ACL's id (the
user who is allowed) to be the authenticated user of the ZK connection.
This results in the HBase superuser not actually receiving the
permissions as the ZKUtil intends to do. Since we know we have security
enabled, we can instead explicitly list "sasl" as the ACL scheme
instead.
Reason for refactor:
In cases where one might need to use multiple observers, say region, master and regionserver; and the fact that only one class can be extended, it gives rise to following pattern:
public class BaseMasterAndRegionObserver
extends BaseRegionObserver
implements MasterObserver
class AccessController
extends BaseMasterAndRegionObserver
implements RegionServerObserver
were BaseMasterAndRegionObserver is full copy of BaseMasterObserver.
There is an example of simple case too where the current design fails.
Say only one observer is needed by the coprocessor, but the design doesn't permit extending even that single observer (see RSGroupAdminEndpoint), that leads to copy of full Bas
e...Observer class into coprocessor class leading to 1000s of lines of code and this ugly mix of 5 main functions with 100 useless functions.
Javadocs changes:
- Adds class comments on 'default' methods and expectations.
- Adds explanaiton of Exception handling in Observers' class comment. Removes redundant @throws before each function.
- Improves javadocs for a bunch of functions
- deletes empty @params in a bunch of places

Addresses review comments by Sean Busbey and Appy that happened
to come in long after the commit of HBASE-6721, the original
rsgroup issue.
Also includes subsequent accommodation of Duo Zhang review.
Adds a new type to hold hostname and port. It is called
Address. It is a facade over Guava's HostAndPort. Replace
all instances of HostAndPort with Address. In particular,
those places where HostAndPort was part of the rsgroup
public API.
Fix licenses. Add audience annotations.
Cleanup and note concurrency expectation on a few core classes.
In particular, all access on RSGroupInfoManager is made
synchronized.

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.

New tool to dump existing replication peers, configurations and
queues when using HBase Replication. The tool provides two flags:
--distributed This flag will poll each RS for information about
the replication queues being processed on this RS.
By default this is not enabled and the information
about the replication queues and configuration will
be obtained from ZooKeeper.
--hdfs When --distributed is used, this flag will attempt
to calculate the total size of the WAL files used
by the replication queues. Since its possible that
multiple peers can be configured this value can be
overestimated.

This is a revert of a revert; i.e. we are adding back the change only adding
back with fixes for the broken unit test; was a real issue on a test that
went in just at same time as this commit; I was getting a new nonce on each
retry rather than getting one for the mutation.
Other changes since revert are more hiding of RpcController. Use
accessor method rather than always pass in a RpcController
Walked back retrying operations that used to be single-shot (though
code comment said need a retry) because it opens a can of worms where
we retry stuff like bad column family when we shouldn't (needs
work adding in DoNotRetryIOEs)

TimeRangeTracker as point of contention when many threads reading a StoreFile
Fixes HBASE-16074 ITBLL fails, reports lost big or tiny families broken

TimeRange construction consistent exposed a latent issue in
TimeRange#compare. See HBASE-16074 for more detail.
Also change HFile Writer constructor so we pass in the TimeRangeTracker, if one,
on construction rather than set later (the flag and reference were not volatile
so could have made for issues in concurrent case). And make sure the construction
of a TimeRange from a TimeRangeTracer on open of an HFile Reader never makes a
bad minimum value, one that would preclude us reading any values from a file

- Testing by executing a command will cover the exact path users will trigger, so its better then directly calling library functions in tests. Changing the tests to use @shell.command(:<command>, args) to execute them like it's a command coming from shell.
Norm change:
Commands should print the output user would like to see, but in the end, should also return the relevant value. This way:
- Tests can use returned value to check that functionality works
- Tests can capture stdout to assert particular kind of output user should see.
- We do not print the return value in interactive mode and keep the output clean. See Shell.command() function.
Bugs found due to this change:
- Uncovered bug in major_compact.rb with this approach. It was calling admin.majorCompact() which doesn't exist but our tests didn't catch it since they directly tested admin.major_compact()
- Enabled TestReplicationShell. If it's bad, flaky infra will take care of it.

Summary:
Currently WAL splitting is broken when a region has been opened multiple times in recent minutes.
Region open and region close write event markers to the wal. These markers should have the sequence id in them. However it is currently getting 1. That means that if a region has moved multiple times in the last few mins then multiple split log workers will try and create the recovered edits file for sequence id 1. One of the workers will fail and on failing they will delete the recovered edits. Causing all split wal attempts to fail.
We need to:
It appears that the close event with a sequence id of one is coming from region warm up.
This patch fixes that by making sure the close on warm up doesn't happen. Also splitting will ignore any of the events that are already in the logs.

Further investigation after HBASE-15221 lead to some findings that
AsyncProcess should have been managing the contents of the region
location cache, appropriately clearing it when necessary (e.g. an
RPC to a server fails because the server doesn't host that region)
For multi() RPCs, the tableName argument is null since there is no
single table that the updates are destined to. This inadvertently
caused the existing region location cache updates to fail on 1.x
branches. AsyncProcess needs to handle when tableName is null
and perform the necessary cache evictions.
As such, much of the new retry logic in HTableMultiplexer is
unnecessary and is removed with this commit. Getters which were
added as a part of testing were left since that are mostly
harmless and should contain no negative impact.

When a Put fails due to a NotServingRegionException, the cached location
of that Region is never cleared. Thus, subsequent calls to resubmit
the Put will fail in the same way as the original, never determining
the new location of the Region.
If the Connection is not closed by the user before the Multiplexer
is discarded, it will leak resources and could cause resource
issues.
