Duo Zhang commented on HBASE-20066: ----------------------------------- Review board link: https://reviews.apache.org/r/65802/ > Region sequence id may go backward after split or merge > ------------------------------------------------------- > > Key: HBASE-20066 > URL: https://issues.apache.org/jira/browse/HBASE-20066 > Project: HBase > Issue Type: Bug > Reporter: Duo Zhang > Assignee: Duo Zhang > Priority: Critical > Fix For: 2.0.0-beta-2 > > Attachments: HBASE-20066.patch > > > The problem is that, now we have markers which will be written to WAL but not > in store file. For a normal region close, we will write a sequence id file > under the region directory, and when opening we will use this as the open > sequence id. But for split and merge, we do not copy the sequence id file to > the newly generated regions so the sequence id may go backwards since when > closing the region we will write flush marker and close marker into WAL... -- This message was sent by Atlassian JIRA (v7.6.3#76005)
