Marton Bod reassigned HIVE-25894:
---------------------------------
Assignee: Marton Bod
> Table migration to Iceberg doesn't remove HMS partitions
> --------------------------------------------------------
>
> Key: HIVE-25894
> URL: https://issues.apache.org/jira/browse/HIVE-25894
> Project: Hive
> Issue Type: Bug
> Reporter: Zoltán Borók-Nagy
> Assignee: Marton Bod
> Priority: Major
>
> Repro:
> {code:java}
> create table ice_part_migrate (i int) partitioned by (p int) stored as
> parquet;
> insert into ice_part_migrate partition(p=1) values (1), (11), (111);
> insert into ice_part_migrate partition(p=2) values (2), (22), (222);
> ALTER TABLE ice_part_migrate SET TBLPROPERTIES
> ('storage_handler'='org.apache.iceberg.mr.hive.HiveIcebergStorageHandler');
> {code}
> Then looking at the HMS database:
> {code:java}
> => select "PART_NAME" from "PARTITIONS" p, "TBLS" t where
> t."TBL_ID"=p."TBL_ID" and t."TBL_NAME"='ice_part_migrate';
> PART_NAME
> -----------
> p=1
> p=2
> {code}
> This is weird because Iceberg tables are supposed to be unpartitioned. It
> also breaks some precondition checks in Impala. Is there a particular reason
> to keep the partitions in HMS?
