patch reverted changes that happened in parallel without explanation. see jira.
This patch adds mirroring of table state out to zookeeper. HBase-1.x
clients look for table state in zookeeper, not in hbase:meta where
hbase-2.x maintains table state.
The patch also moves and refactors the 'migration' code that was put in
place by HBASE-13032.
D hbase-client/src/main/java/org/apache/hadoop/hbase/CoordinatedStateException.java
Unused.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/HMaster.java
Move table state migration code from Master startup out to
TableStateManager where it belongs. Also start
MirroringTableStateManager dependent on config.
A hbase-server/src/main/java/org/apache/hadoop/hbase/master/MirroringTableStateManager.java
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/TableStateManager.java
Move migration from zookeeper of table state in here. Also plumb in
mechanism so subclass can get a chance to look at table state as we do
the startup fixup full-table scan of meta.
M hbase-server/src/main/java/org/apache/hadoop/hbase/master/assignment/AssignmentManager.java
Bug-fix. Now we create regions in CLOSED state but we fail to check
table state; were presuming table always enabled. Meant on startup
there'd be an unassigned region that never got assigned.
A hbase-server/src/test/java/org/apache/hadoop/hbase/master/TestMirroringTableStateManager.java
Test migration and mirroring.
If the initial state is not set to CLOSED while creating merged/ children region/s, merged/
children region/s get stored in meta with state OFFLINE(0). If the master gets restarted after
Merge/ Split procedure stores merged/ children region/s, master startup sequence tries to assign
offline region/s. This is followed by re-assignment of merged/ children region from resumed Merge/
Split procedure.
This bug is related to HBASE-19530.

First, we add test resources to CLASSPATH when tests run. W/o it, there
was no logging of hbase-zookeeper test output (not sure why I have to
add this here and not over in hbase-server; research turns up nothing
so far).
M hbase-zookeeper/src/main/java/org/apache/hadoop/hbase/zookeeper/ZKMainServer.java
Improve fail log message.
M hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestReadOnlyZKClient.java
M hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestZKNodeTracker.java
Wait until ZK is connected before progressing. On my slow zk, it could
be a while post construction before zk connected. Using an unconnected
zk caused test to fail.
M hbase-zookeeper/src/test/java/org/apache/hadoop/hbase/zookeeper/TestZKMainServer.java
Change session timeout to default 30s from 1s which was way too short.
M hbase-zookeeper/src/test/resources/log4j.properties
Set zk logs to DEBUG level in this module at least.
Adds a ZooKeeperHelper class that has utility to help interacting w/ ZK.
Adds (client-side) validation to ReplicationPeerConfigBuilder and javadoc
to builder methods in addition to the test fix.
