--------------------------
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
