             Summary: Hbase index partition changes cause data duplication problems
                 Key: HUDI-1347
                 URL: https://issues.apache.org/jira/browse/HUDI-1347
             Project: Apache Hudi
          Issue Type: Bug
          Components: Index
            Reporter: jing
            Assignee: jing


1,A piece of data repeatedly changes the partition. After the data deduplication operation, the partition information of the key and data in the HoodieRecord object is inconsistent.

E.g:

id,oid,name,dt,isdeleted,lastupdatedttm,rowkey
9,1,aaaa,2018,0,2020-02-17 00:50:25.000001,00_test1-9-1
9,1,aaaa,2019,0,2020-02-17 00:50:25.000002,00_test1-9-1

rowkey is the primary key and dt is the partition. After deduplication, the key of the HoodieRecord object is (00_test1-9-1,2018).The key should be (00_test1-9-1,2019)

2,An exception in the hudi task caused the hbase index to be written successfully but the task failed. If the task is retried, the partition change data becomes only a new creation. The data before the partition change is not deleted.

Solution:

1,Fixed the error of partition information in HoodieRecord key caused by deduplication operation

2.The hbase index adds a rollback operation instead of doing nothing. The partition change needs to be rolledback to the index of the last successful commit。

3.Rich test cases
