Subject [jira] [Commented] (HBASE-17407) Correct update of maxFlushedSeqId in HRegion
Date Tue, 03 Jan 2017 09:35:58 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17407?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15794629#comment-15794629
] 

Duo Zhang commented on HBASE-17407:
-----------------------------------

Can we just remove the finalizeFlush method? It does not make sense to maintain an incorrect
flushed sequence id in WAL and then reset it to the correct value...

> The attribute maxFlushedSeqId in HRegion is used to track the max sequence id in the
store files and is reported to HMaster. When flushing only part of the memstore content this
value might be incorrect and may cause data loss.
