Thanks > After droped the table, using snapshot recovery to cause data consistency > problems > ---------------------------------------------------------------------------------- > > Key: HBASE-25429 > URL: https://issues.apache.org/jira/browse/HBASE-25429 > Project: HBase > Issue Type: Bug > Reporter: wxzkenny > Priority: Major > > 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 tablea > 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. -- This message was sent by Atlassian Jira (v8.3.4#803005)
