---------------------------------------
Fix Version/s: 0.8.0
Resolution: Fixed
> 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
> Priority: Major
> Labels: pull-request-available, sev:critical, user-support-issues
> Fix For: 0.8.0
>
>
> 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
