Abhishek Madav updated SPARK-20697:
-----------------------------------
Description:
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
