Heng Chen updated HBASE-14949: ------------------------------ Attachment: HBASE-14949_v2.patch Fixing of WAL file name conflict after splitting and add one testcase for it. > Skip duplicate entries when replay WAL. > --------------------------------------- > > Key: HBASE-14949 > URL: https://issues.apache.org/jira/browse/HBASE-14949 > Project: HBase > Issue Type: Sub-task > Reporter: Heng Chen > Attachments: HBASE-14949.patch, HBASE-14949_v1.patch, > HBASE-14949_v2.patch > > > As HBASE-14004 design, there will be duplicate entries in different WAL. It > happens when one hflush failed, we will close old WAL with 'acked hflushed' > length, then open a new WAL and write the unacked hlushed entries into it. > So there maybe some overlap between old WAL and new WAL. > We should skip the duplicate entries when replay. I think it has no harm to > current logic, maybe we do it first. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
