-----------------------------------
Summary: Replaying recovered edits would make deleted data exist
again
Key: HBASE-6059
URL: https://issues.apache.org/jira/browse/HBASE-6059
Project: HBase
Issue Type: Bug
Components: regionserver
Reporter: chunhui shen
Assignee: chunhui shen
When we replay recovered edits, we used the minSeqId of Store, It may cause
deleted data appeared again.
Let's see how it happens. Suppose the region with two families(cf1,cf2)
1.put one data to the region (put r1,cf1:q1,v1)
2.move the region from server A to server B.
3.delete the data put by step 1(delete r1)
4.flush this region.
5.make major compaction for this region
6.move the region from server B to server A.
7.Abort server A
8.After the region is online, we could get the deleted data(r1,cf1:q1,v1)
(When we replay recovered edits, we used the minSeqId of Store, because cf2 has
no store files, so its seqId is 0, so the edit log of put data will be replayed
to the region)
