Adesh Kumar Rao reassigned HIVE-23358:
--------------------------------------
> MSCK repair should remove all zeroes from partition values before creating
> the partitions
> -----------------------------------------------------------------------------------------
>
> Key: HIVE-23358
> URL: https://issues.apache.org/jira/browse/HIVE-23358
> Project: Hive
> Issue Type: Bug
> Components: Standalone Metastore
> Affects Versions: 4.0.0
> Reporter: Adesh Kumar Rao
> Assignee: Adesh Kumar Rao
> Priority: Major
>
> For the following scenario
> 1. Have partitioned data path as follows.
> hdfs://mycluster/datapath/t1/year=2020/month=03/day=10
> hdfs://mycluster/datapath/t1/year=2020/month=03/day=11
> 2. create external table t1 (key int, value string) partitioned by (Year int,
> Month int, Day int) stored as orc location hdfs://mycluster/datapath/t1'';
> 3. msck repair table t1;
> 4. show partitions t1;
> {noformat}
> +----------------------------+
> | partition |
> +----------------------------+
> | year=2020/month=03/day=10 |
> | year=2020/month=03/day=11 |
> +----------------------------+
> {noformat}
> 5.show table extended like 't1' partition (Year=2020, Month=03, Day=11);
> will throw an error:
> {noformat}
> Error: Error while compiling statement: FAILED: SemanticException [Error
> 10006]: Partition not found {year=2020, month=3, day=11}
> (state=42000,code=10006)
> {noformat}
> When the partition directory are created without the extra zeroes, this works
> fine.
> {noformat}
> hdfs://mycluster/datapath/t1/year=2020/month=3/day=10
> hdfs://mycluster/datapath/t1/year=2020/month=3/day=11
> {noformat}
> This happens because while searching for partitions, hive strips the extra
> "0" in month key and then queries the metastore
> (partSpec="year=2020/month=3/day=10") which returns no rows.
