Decouple the HBase internals such that someone can implement
their own SASL-based authentication mechanism and plug it into
HBase RegionServers/Masters.
Comes with a design doc in dev-support/design-docs and an example in
hbase-examples known as "Shade" which uses a flat-password file
for authenticating users.

The current process for an operator, after fixing holes in meta, is to
manually disable and enable the whole table. Let's try to avoid
bringing the whole table offline if we can. Have the master attempt to
queue up assignment procedures for any new regions it creates.

The cleanupBulkLoad method is only called for the first Region in the
table which was being bulk loaded into. This means that potentially N-1
other RegionServers (where N is the number of RegionServers) will leak
one FileSystem object into the FileSystem cache which will never be
cleaned up. We need to do this clean-up as a part of secureBulkLoadHFiles
otherwise we cannot guarantee that heap usage won't grow unbounded.

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.

Throw illegal access exception if you try to use MetaTableAccessor
getting state of the hbase:meta table.

Add fetching of hbase:meta table state from registry. Adds cache of

Add querying of mirrored table state for hbase:meta table.

Added a note and small refactor.

Fix an NPE when CJ ran.

Minor clean up of log message; make it clearer.

Make it so closeRegionSilentlyAndWait can be used w/o timeout.

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)

Minor tweak of toString -- label should be state, not rit (confusing).

Add region name to exception.

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'.
