Purges Server, MasterServices, and RegionServerServices from
CoprocessorEnvironments. Replaces removed functionality with
a set of carefully curated methods on the *CoprocessorEnvironment
implementations (Varies by CoprocessorEnvironment in that the
MasterCoprocessorEnvironment has Master-type facility exposed,
and so on).
A few core Coprocessors that should long ago have been converted
to be integral, violate their context; e.g. a RegionCoprocessor
wants free access to a hosting RegionServer (which may or may not
be present). Rather than let these violators make us corrupte the
CP API, instead, we've made up a hacky system that allows core
Coprocessors access to internals. A new CoreCoprocessor Annotation
has been introduced. When loading Coprocessors, if the instance is
annotated CoreCoprocessor, we pass it an Environment that has been
padded w/ extra-stuff. On invocation, CoreCoprocessors know how to
route their way to these extras in their environment.
See the *CoprocessoHost for how the do the check for CoreCoprocessor
and pass a fatter *Coprocessor, one that allows getting of either
a RegionServerService or MasterService out of the environment
via Marker Interfaces.
Removed org.apache.hadoop.hbase.regionserver.CoprocessorRegionServerServices
M hbase-endpoint/src/main/java/org/apache/hadoop/hbase/security/access/SecureBulkLoadEndpoint.java
This Endpoint has been deprecated because its functionality has been
moved to core. Marking it a CoreCoprocessor in the meantime to
minimize change.
M hbase-rsgroup/src/main/java/org/apache/hadoop/hbase/rsgroup/RSGroupAdminEndpoint.java
This should be integral to hbase. Meantime, marking it CoreCoprocessor.
M hbase-server/src/main/java/org/apache/hadoop/hbase/Server.java
Added doc on where it is used and added back a few methods we'd
removed.
A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/CoreCoprocessor.java
New annotation for core hbase coprocessors. They get richer environment
on coprocessor loading.
A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/HasMasterServices.java
A hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/HasRegionServerServices.java
Marker Interface to access extras if present.
M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/MasterCoprocessorEnvironment.java
Purge MasterServices access. Allow CPs a Connection.
M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionCoprocessorEnvironment.java
Purge RegionServerServices access. Allow CPs a Connection.
M hbase-server/src/main/java/org/apache/hadoop/hbase/coprocessor/RegionServerCoprocessorEnvironment.java
Purge MasterServices access. Allow CPs a Connection.
M hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/MasterSpaceQuotaObserver.java
M hbase-server/src/main/java/org/apache/hadoop/hbase/quotas/QuotaCache.java
We no longer have access to MasterServices. Don't need it actually.
Use short-circuiting Admin instead.
D hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/CoprocessorRegionServerServices.java
Removed. Not needed now we do CP Env differently.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
No need to go via RSS to getOnlineTables; just use HRS.
And so on. Adds tests to ensure we can only get at extra info
if the CP has been properly marked.
- Table moving to RSG was buggy, because it left the table unassigned.
Now it is fixed we immediately assign to an appropriate RS
(MoveRegionProcedure).
- Table was locked while moving, but unassign operation hung, because
locked table queues are not scheduled while locked. Fixed.
- ProcedureSyncWait was buggy, because it searched the procId in
executor, but executor does not store the return values of internal
operations (they are stored, but immediately removed by the cleaner).
- list_rsgroups in the shell show also the assigned tables and servers.

* batch validation and preparation is done before we start iterating over operations for writes
* durability, familyCellMaps and observedExceptions are batch wide and are now sotred in BatchOperation,
as a result durability is consistent across all operations in a batch
* for all operations done by preBatchMutate() CP hook, operation status is updated to success
* doWALAppend() is modified to habdle replay and is used from doMiniBatchMutate()
* minor improvements

The archived Procedure WALs are moved to <hbase_root>/oldWALs/masterProcedureWALs
directory. TimeToLiveProcedureWALCleaner class was added which
regularly cleans the Procedure WAL files from there.
The TimeToLiveProcedureWALCleaner is now added to
hbase.master.logcleaner.plugins to clean the 2 WALs in one run.
A new config parameter is added hbase.master.procedurewalcleaner.ttl
which specifies how long a Procedure WAL should stay in the
archive directory.
