wxzkenny created HBASE-25428: -------------------------------- Summary: data inconsistency problem Key: HBASE-25428 URL: https://issues.apache.org/jira/browse/HBASE-25428 Project: HBase Issue Type: Bug Reporter: wxzkenny
We discovered a consistency problem during use HBase. The cause of the problem should be that after the table is dropped, when the snapshot is restored, in some cases the wal log will be applied, thereby the wal log of the dropped table restored to the restored table, because their region id are the same. Steps to reproduce: 1. Create a table 2. Make a snapshot1 3. Insert some records r1 4. Drop the table 5. Restore snapshot 1 6. Down RS or move the region, etc., wal is reapplied You may see the data r1 in the snapshot1 table. The problem is not a stable recurrence, but there is a certain probability that it can recur. it looks like the problem: https://issues.apache.org/jira/browse/HBASE-23741 It will still appear after we apply the relevant patch -- This message was sent by Atlassian Jira (v8.3.4#803005)
