------------------------------------------
Summary: Partition transactional table is not updated on alter
partition when hms_event_incremental_refresh_transactional_table is disabled
Key: IMPALA-13141
URL: https://issues.apache.org/jira/browse/IMPALA-13141
Project: IMPALA
Issue Type: Bug
Reporter: Venugopal Reddy K
Partition transactional table is not updated on alter partition when
hms_event_incremental_refresh_transactional_table is disabled.
*Observations:*
1. In case of AlterPartitionEvent, this issue occurs when
hms_event_incremental_refresh_transactional_table is disabled.
2. In case of BatchPartitionEvent(when. more than 1
AlterPartitionEvent are batched together), this issue occurs without disabling
hms_event_incremental_refresh_transactional_table.
*Steps to reproduce:*
1. Create partitioned table and add some partitions from hive:
Note: This step can be from impala too.
{code:java}
0: jdbc:hive2://localhost:11050> create table s(i int, j int, p int);
0: jdbc:hive2://localhost:11050> insert into s values(1,10,100),(2,20,200);
{code}
{code:java}
0: jdbc:hive2://localhost:11050> create table test1(i int, j int) partitioned
by(p int) tblproperties ('transactional'='true',
'transactional_properties'='insert_only');
0: jdbc:hive2://localhost:11050> set hive.exec.dynamic.partition.mode=nonstrict;
0: jdbc:hive2://localhost:11050> insert into test partition(p) select * from s;
0: jdbc:hive2://localhost:11050> show partitions test;
+------------+
| partition |

| p=100 |
| p=200 |
+------------+
0: jdbc:hive2://localhost:11050> desc formatted test partition(p=100);

2. Check for the partitions and its locations from impala shell:
{code:java}

3. Alter partition location from hive:
{code:java}
0: jdbc:hive2://localhost:11050> alter table test1 partition(p=100) set
location '/dummylocation100';
0: jdbc:hive2://localhost:11050> desc formatted test partition(p=100);
