------------------------------------
Summary: Introducing "recovering" region state to mark a region in
recovering status used in distributedLogReplay
Key: HBASE-8234
URL: https://issues.apache.org/jira/browse/HBASE-8234
Project: HBase
Issue Type: Sub-task
Reporter: Jeffrey Zhong
There are two advantages to have this new "recovering" state for a region:
1) Instead of mark a region "recovering" in ZK, we can consolidate all region
states in one place and be aware by assignment manager
2) When handing disabling table, we have to have this new state so that regions
of a disabling table can be transitioned into this state for recovering.
Notes:
In the initial release of distributed log replay, we may not do this subtask
for simplifications. Without the new state, we still need to create recovered
edits files for regions of a disabling table. With the new state, we can retire
recover edits files creation business totally.
