--------------------------------------
Summary: Don't copy the replication queue which belong to the peer
have been deleted
Key: HBASE-17077
URL: https://issues.apache.org/jira/browse/HBASE-17077
Project: HBase
Issue Type: Improvement
Reporter: Guanghao Zhang
Assignee: Guanghao Zhang
Priority: Minor
When a region server is dead, then other live region servers will transfer the
dead rs's replication queue to their own queue. Now the live rs first copy the
wals queue to its own znode, then create a new replication source to replicate
the wals. But if the queue belong to a peer have been deleted, it copy the
queue, too. The current steps is:
1. copy the queue to its own znode
2. found the queue belong to a peer have been deleted
3. remove the queue and don't create a new replication source for it
There is a small improvement. The live region server doesn't need to copy the
queue to its own znode. The new steps is:
1. found the queue belong to a peer have been deleted
2. remove the queue directly instead of copy it
