We have a compile-time guarantee to either have a category array
of length zero or one because the category annotation is non-repeatable.
Also tries to clean up the checking for unit-test annotations.

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.

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.

All the clients need to know the master RPC end points while using master
based registry for creating cluster connections. This patch amends the
test cluster utility to populate these configs in the base configuration
object used to spin up the cluster.
The config key added here ("hbase.master.addrs") is used in the subsequent
patches for HBASE-18095.

Removes the closeRegion flag added by HBASE-23181 and instead
relies on reading meta WALEdit content. Modified how qualifier is
written when the meta WALEdit is for a RegionEventDescriptor
so the 'type' is added to the qualifer so can figure type
w/o having to deserialize protobuf value content: e.g.
HBASE::REGION_EVENT::REGION_CLOSE
Added doc on WALEdit and tried to formalize the 'meta' WALEdit
type and how it works. Needs complete redo in part as suggested
by HBASE-8457. Meantime, some doc and cleanup.
Also changed the LogRoller constructor to remove redundant param.
Because of constructor change, need to change also

For table state, go to master rather than go to meta direct. Going
to meta won't work for hbase;meta state. Puts load on Master.

Change isTableDisabled/Enabled implementation to ask the Master instead.
This will give the Master's TableStateManager's opinion rather than

Makes MergeTableRegionsProcedure do more than just two regions at a
time. Compatible as MTRP was done considering one day it'd do more than
two at a time.
Changes hardcoded assumption that merge parent regions are named
mergeA and mergeB in a column on the resultant region. Instead
can have N columns on the merged region, one for each parent
merged. Column qualifiers all being with 'merge'.
Most of code below is undoing the assumption that there are two
parents on a merge only.
Refactor of CatalogJanitor so it generates a
Report on the state of hbase:meta when it runs. Also
refactor so CJ runs even if RIT (previous it would
punt on running if RIT) so it can generate a 'Report'
on the interval regardless. If RIT, it just doesn't
go on to do the merge/split GC as it used to.
If report finds an issue, dump as a WARN message
to the master log.
Follow-on is to make the Report actionable/available
for the Master to pull when it goes to draw the hbck
UI page (could also consider shipping the Report as
part of ClusterMetrics?)
Adds new, fatter Visitor to CJ, one that generates
Report on each run keeping around more findings as
it runs.
Moved some methods around so class reads better;
previous methods were randomly ordered in the class.
M hbase-client/src/main/java/org/apache/hadoop/hbase/MetaTableAccessor.java

M hbase-client/src/main/java/org/apache/hadoop/hbase/client/RegionInfo.java
Add utility as defaults on the Inteface; i.e. is this the first region
in table, is it last, does a passed region come next, or does passed
region overlap this region (added tests for this new stuff).
