HBASE-26482 HMaster may clean wals that is replicating in rare cases #3887
Conversation
There is a problem. We can't update cversion of root queuesZnode atomically when hbase.zookeeper.useMulti is set false. Now, I only fixed this problem when hbase.zookeeper.useMulti true. (default is true) Another way to totally solve this problem: Check cversion of /hbase/replication/rs and all znodes of /hbase/replication/rs/${servername} when master clean. But this way will cause the code of branch-1 different with master. I don't know which is better. |
I think it is OK to have different code implementation for branch-1. |
