Duo Zhang commented on HBASE-14949: ----------------------------------- {quote} if my question on use of formatRecoveredEditsFileName from other context has simple answer {quote} Got it. Let me check the references to this method. > Resolve name conflict when splitting if there are duplicated WAL entries > ------------------------------------------------------------------------ > > Key: HBASE-14949 > URL: https://issues.apache.org/jira/browse/HBASE-14949 > Project: HBase > Issue Type: Sub-task > Reporter: Heng Chen > Assignee: Duo Zhang > Attachments: HBASE-14949-v3.patch, HBASE-14949-v4.patch, > HBASE-14949.patch, HBASE-14949_v1.patch, HBASE-14949_v2.patch > > > The AsyncFSHLog introduced in HBASE-14790 may write same WAL entries to > different WAL files. WAL entry itself is idempotent so replay is not a > problem but the intermediate file name and final name when splitting is > constructed using the lowest or highest sequence id of the WAL entries > written, so it is possible that different WAL files will have same > intermediate or final file name when splitting. In the currentm > implementation, this will cause split fail or data loss. We need to solve > this. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
