Make hbase:meta region schema dynamic.
Patch has been under development a good while and its focus has changed
a few times so its bloated with fixup from older versions.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/TableStateManager.java
M hbase-client/src/main/java/org/apache/hadoop/hbase/zookeeper/ZNodePaths.java
Shut down access to internals and removed unused methods.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/EnableTableProcedure.java
Cleanup/refactor section on replica-handling.
M hbase-server/src/main/java/org/apache/hadoop/hbase/util/FSTableDescriptors.java
Get hbase:meta schema from filesystem rather than from hard-coding.
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/HBaseAdmin.java
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.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/procedure/DisableTableProcedure.java
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.

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.
