> Key: SPARK-20697
> URL: https://issues.apache.org/jira/browse/SPARK-20697
> Project: Spark
> Issue Type: Bug
> Components: SQL
> Affects Versions: 2.1.0, 2.2.0, 2.2.1, 2.3.0
> Reporter: Abhishek Madav
> Priority: Major
>
> MSCK REPAIR TABLE used to recover partitions for a partitioned+bucketed table
> does not restore the bucketing information to the storage descriptor in the
> metastore.
> Steps to reproduce:
> 1) Create a paritioned+bucketed table in hive: CREATE TABLE partbucket(a int)
> PARTITIONED BY (b int) CLUSTERED BY (a) INTO 10 BUCKETS ROW FORMAT DELIMITED
> FIELDS TERMINATED BY ',';
> 2) In Hive-CLI issue a desc formatted for the table.
> # col_name data_type comment
>
> a int
>
> # Partition Information
> # col_name data_type comment
>
> b int
>
> # Detailed Table Information
> Database: sparkhivebucket
> Owner: devbld

> 3) In spark-shell,

> 4) Back to Hive-CLI
> desc formatted partbucket;
> # col_name data_type comment
