* HBASE-23601: OutputSink.WriterThread exception gets stuck and repeated indefinietly
clear exception after logged
try to restart writer threads if needed
Make it so hbase:meta can be altered. TableState for hbase:meta
was hardcoded ENABLED. Make it dynamic. State is now kept in
current active Master. It is transient so falls back to default
if Master crashes. Add to registry a getMetaTableState
which reads mirrored state from zookeeper (NOT from Master and
defaults ENABLED if no implementation or error fetching state).
hbase:meta schema will be bootstrapped from the filesystem.
Changes to filesystem schema are atomic so we should be ok if
Master fails mid-edit (TBD). Undoes a bunch of guards that
prevented our being able to edit hbase:meta.
TODO: Tests, more clarity around hbase:meta table state, and undoing
references to hard-coded hbase:meta regioninfo.
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Throw illegal access exception if you try to use MetaTableAccessor
getting state of the hbase:meta table.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/ConnectionImplementation.java
Add fetching of hbase:meta table state from registry. Adds cache of
tablestates w/ a ttl of 1 second (adjustable).

M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RawAsyncHBaseAdmin.java
Add querying registry for hbase:meta table state.
M hbase-client/src/main/java/org/apache/hadoop/hbase/client/ZKAsyncRegistry.java
Add querying of mirrored table state for hbase:meta table.
M hbase-client/src/main/java/org/apache/hadoop/hbase/zookeeper/ZNodePaths.java
Shutdown access.
M hbase-server/src/main/java/org/apache/hadoop/hbase/TableDescriptors.java
Just cleanup.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/TableStateManager.java
Add state holder for hbase:meta. Removed unused methods.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStateStore.java
Shut down access.

Allow hbase:meta to be disabled.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/EnableTableProcedure.java
Allow hbase:meta to be enabled.

Master force-closes unknown/incorrect Regions OPEN on RS
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java
Added a note and small refactor.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java
Fix an NPE when CJ ran.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Minor clean up of log message; make it clearer.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/ServerManager.java
Make it so closeRegionSilentlyAndWait can be used w/o timeout.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
If a RegionServer Report notes a Region is OPEN and the Master does not
know of said Region, close it (We used to crash out the RegionServer)
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionStateNode.java
Minor tweak of toString -- label should be state, not rit (confusing).

Doc.

Add region name to exception.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/HBCKServerCrashProcedure.java
Be more careful about which Regions we queue up for reassign. This
procedure is run by the operator so could happen at any time. We
will likely be running this when Master has some accounting of
cluster members so check its answers for what Regions were on
server before running.
M hbase-server/src/main/java/org/apache/hadoop/hbase/regionserver/HRegionServer.java
Doc and we were misrepresenting the case where a Region as not in RIT
when we got CLOSE -- we were reporting it as though it was already
trying to CLOSE.

Change its behavior so it will only look in hbase:meta
if the call to the super class turns up zero references.
Only then will it search hbase:meta for references to
'Unknown Servers'. Normal operation where we read Master
context is usual and sufficient. The scan of hbase:meta
is only for case where Master state has been corrupted
and we need to clear out 'Unknown Servers'.
Having it as static means the test cannot be parameterized (ran into
this issue in HBASE-23305). That happens because the field is not
reset between parameterized runs.
