As part of HBASE-18978 the rpc timeout methods gets aligned
between Table and AsyncTable interfaces.
Deprecate the following methods in Table:
- int getRpcTimeout()
- int getReadRpcTimeout()
- int getWriteRpcTimeout()
- int getOperationTimeout()
Add the following methods to Table:
- long getRpcTimeout(TimeUnit)
- long getReadRpcTimeout(TimeUnit)
- long getWriteRpcTimeout(TimeUnit)
- long getOperationTimeout(TimeUnit)
Fix some javadoc issues.

Change name of Interface OnlineRegions to MutableOnlineRegions.
Change name of Interface ImmutableOnlineRegions to OnlineRegions.
Did this since OnlineRegions is for consumer other than internals.
Add a getOnlineRegions to the RegionCoprocessorEnvironment and to
RegionServerCoprocessorEnvironment so CPs can 'access' local
Regions directly.
- Merged BaseCSM class into CSM interface
- Removed config hbase.coordinated.state.manager.class
- Since state manager is not pluggable anymore, we don't need start/stop/initialize to setup unknown classes. Our internal ZkCSM now requires Server in constructor itself. Makes the dependency clearer too.
- Removed CSM from HRegionServer and HMaster constructor. Although it's a step back from dependency injection, but it's more consistent with our current (not good) pattern where we initialize everything in the ctor itself.

Breaks MemStoreSize into MemStoreSize (read-only) and MemStoreSizing
(read/write). MemStoreSize we allow to Coprocesors. MemStoreSizing we
use internally doing MemStore accounting.
Patch to start a standalone RegionServer that register's itself and
optionally stands up Services. Can work w/o a Master in the mix.
Useful testing. Also can be used by hbase-indexer to put up a
Replication sink that extends public-facing APIs w/o need to extend
internals. See JIRA release note for detail.
This patch adds booleans for whether to start Admin and Client Service.
Other refactoring moves all thread and service start into the one fat
location so we can ask to by-pass 'services' if we don't need them.
See JIRA for an example hbase-server.xml that has config to shutdown
WAL, cache, etc.
Adds checks if a service/thread has been setup before going to use it.
Renames the ExecutorService in HRegionServer from service to
executorService.
See JIRA too for example Connection implementation that makes use of
Connection plugin point to receive a replication stream. The default
replication sink catches the incoming replication stream, undoes the
WALEdits and then creates a Table to call a batch with the
edits; up on JIRA, an example Connection plugin (legit, supported)
returns a Table with an overridden batch method where in we do index
inserts returning appropriate results to keep the replication engine
ticking over.
Upsides: an unadulterated RegionServer that will keep replication metrics
and even hosts a web UI if wanted. No hacks. Just ordained configs
shutting down unused services. Injection of the indexing function at a
blessed point with no pollution by hbase internals; only public imports.
No user of Private nor LimitedPrivate classes.
A hack to "hide" the protobufs, but it's not going to be a trivial
change to remove use of protobufs entirely as they're serialized
into the hbase:quota table.
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.
