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.
