--------------------------------------
Summary: MSCK REPAIR TABLE resets the Storage Information for
bucketed hive tables.
Key: SPARK-20697
URL: https://issues.apache.org/jira/browse/SPARK-20697
Project: Spark
Issue Type: Bug
Components: SQL
Affects Versions: 2.1.0
Reporter: Abhishek Madav
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

Location: hdfs://localhost:8020/user/hive/warehouse/partbucket
Table Type: MANAGED_TABLE
Table Parameters:
transient_lastDdlTime 1494437467
# Storage Information
SerDe Library: org.apache.hadoop.hive.serde2.lazy.LazySimpleSerDe
InputFormat: org.apache.hadoop.mapred.TextInputFormat

Storage Desc Params:

3) In spark-shell,
scala> spark.sql("MSCK REPAIR TABLE partbucket")
4) Back to Hive-CLI
desc formatted partbucket;
# col_name data_type comment
a int
# Partition Information
# col_name data_type comment
b int
# Detailed Table Information
