Ted Yu commented on HBASE-4645: ------------------------------- The TODO should refer to HBASE-3149 I will add a cross reference in HBASE-3149 to this JIRA. Nice job, Amit. > Edits Log recovery losing data across column families > ----------------------------------------------------- > > Key: HBASE-4645 > URL: https://issues.apache.org/jira/browse/HBASE-4645 > Project: HBase > Issue Type: Bug > Affects Versions: 0.89.20100924, 0.92.0 > Reporter: Amitanand Aiyer > Assignee: Amitanand Aiyer > > There is a data loss happening (for some of the column families) when we do > the replay logs. > The bug seems to be from the fact that during replay-logs we only choose to > replay > the logs from the maximumSequenceID across *ALL* the stores. This is wrong. > If a > column family is ahead of others (because the crash happened before all the > column > families were flushed), then we lose data for the column families that have > not yet > caught up. > The correct logic for replay should begin the replay from the minimum across > the > maximum in each store. -- This message is automatically generated by JIRA.
