> Null pointer exception for update query on a partitioned acid table
> -------------------------------------------------------------------

> Key: HIVE-22067
> URL: https://issues.apache.org/jira/browse/HIVE-22067
> Project: Hive
> Issue Type: Bug
> Components: Transactions
> Affects Versions: 3.1.1
> Reporter: Aditya Shah
> Assignee: Aditya Shah
> Priority: Major
> Attachments: HIVE-22067.1.patch, HIVE-22067.patch

>
> In case of an acid table, the final paths (array) of the filesink operator is
> populated by using bucket id as the index. This causes the final paths to
> have null entries when we don't write to some of the buckets. Thus, finally
> while committing the paths in closeOp this results in an NPE.
> Observed for the following query:
> {code:java}
> CREATE TABLE if not exists test_bckt_part(a int) partitioned by (b int)
> stored as orc;
> CREATE TABLE test_src_delete (a int, b int) CLUSTERED BY (b) into 5 BUCKETS;
> INSERT INTO TABLE test_src_delete values
> (1,2),(3,4),(5,2),(7,8),(9,10),(11,2),(34,53),(95,23),(1,2),(3,4),(5,2),(7,8),(9,10),(11,2),(34,53),(95,23);
> set tez.grouping.split-count=5;
> INSERT OVERWRITE TABLE test_bckt_part SELECT * FROM test_src_delete;
> Alter table test_bckt_part SET TBLPROPERTIES ('transactional'='true');
> update test_bckt_part set a=99 where b=23;
> {code}
