Duo Zhang resolved HBASE-20568. ------------------------------- Resolution: Not A Problem After HBASE-20424 the problem is gone. > Concurrency issue for CombinedAsyncWriter > ----------------------------------------- > > Key: HBASE-20568 > URL: https://issues.apache.org/jira/browse/HBASE-20568 > Project: HBase > Issue Type: Sub-task > Reporter: Duo Zhang > Priority: Major > > In sequential mode, we need to wait for the previous writer's sync completes > before issue the sync for the next writer. But the sync request is > asynchronous, so we will return immediately and then we can call append, so > it is possible that we call append and sync at the same time and cause > concurrency issues. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
