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
Make a few handy methods public.
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).
M hbase-common/src/main/java/org/apache/hadoop/hbase/util/Bytes.java
Bugfix... handle case where buffer passed is null.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/CatalogJanitor.java
Lots of change, reorg., but mostly adding consistency checking
to the visitor used scanning hbase:meta on a period and the
generation of a Report on what the scan has found traversing
hbase:meta. Added a main so could try the CatalogJanitor against
a running cluster.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestCatalogJanitorCluster.java
Fat ugly test for CatalogJanitor consistency checking.
M hbase-server/src/test/java/org/apache/hadoop/hbase/regionserver/TestHRegionInfo.java
Add tests for new functionality in RI.
M hbase-shell/src/main/ruby/hbase/table.rb
Bug fix for case where meta has a null regioninfo; scan was aborting.

Adds override to assigns and unassigns. Changes bypass 'force'
to align calling the param 'override' instead.
Adds recursive to 'bypass', a means of calling bypass on
parent and its subprocedures (usually bypass works on
leaf nodes rippling the bypass up to parent -- recursive
has us work in the opposite direction): EXPERIMENTAL.
bypass on an assign/unassign leaves region in RIT and the
RegionStateNode loaded with the bypassed procedure. First
implementation had assign/unassign cleanup leftover state.
Second implementation, on feedback, keeps the state in place
as a fence against other Procedures assuming the region entity,
and instead adds an 'override' function that hbck2 can set on
assigns/unassigns to override the fencing.
Note that the below also converts ProcedureExceptions that
come out of the Pv2 system into DoNotRetryIOEs. It is a
little awkward because DNRIOE is in client-module, not
in procedure module. Previous, we'd just keep retrying
the bypass, etc.
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/Procedure.java
Have bypass take an environment like all other methods so subclasses.
Fix javadoc issues.
M hbase-procedure/src/main/java/org/apache/hadoop/hbase/procedure2/ProcedureExecutor.java
Javadoc issues. Pass environment when we invoke bypass.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Rename waitUntilNamespace... etc. to align with how these method types
are named elsehwere .. i.e. waitFor rather than waitUntil..
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/RegionTransitionProcedure.java
Cleanup message we emit when we find an exisitng procedure working
against this entity.
Add support for a force function which allows Assigns/Unassigns force
ownership of the Region entity.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/assignment/TestRegionBypass.java
Test bypass and force.
M hbase-shell/src/main/ruby/shell/commands/list_procedures.rb
Minor cleanup of the json output... do iso8601 timestamps.
This reverts commit b96905d1df.
i.e. a revert of a revert so a reapplication!
Revert so I can add signed-off-by....
