> Hi,
> There's is a bug while running MSCK REPAIR TABLE EXTERNAL_TABLE_NAME on
> Hive 1.2.1, all the partition that are not present in the metastore are being
> listed but not added if the partition names are not in lowercase, in other
> words if an external path has a camel case based name and value i.e
> s3n://some_external_path/myPartition=01 it just gets listed as partition not
> found in metastore but doesn’t add it.
> However, am not able to run ALTER TABLE MY_EXTERNAL_TABLE RECOVER PARTITIONS;
> on hive 1.2 and based on the source code from hive-exec am able to see under
> org/apache/hadoop/hive/ql/parse/HiveParser.g:1001:1 that there's no token
> matching in the grammar for RECOVER PARTITIONS.
> Example:
> - When external path = s3n://some_external_path/myPartition=01
> hive> MSCK REPAIR TABLE my_external_table;
> Partitions not in metastore: my_external_table:mypartition=01
> Time taken: 1.729 seconds, Fetched: 2 row(s)
> hive> show partitions foster.ola_raven_raven_users_raw;
> OK
> Time taken: 0.901 seconds, Fetched: 0 row(s)
> - When external path = s3n://some_external_path/mypartition=01
> hive> MSCK REPAIR TABLE my_external_table;
> Partitions not in metastore: my_external_table:mypartition=01
> Repair: Added partition to metastore my_external_table:mypartition=01
> Time taken: 1.729 seconds, Fetched: 2 row(s)
> hive> show partitions my_external_table;
> OK
> mypartition=01
> Time taken: 1.101 seconds, Fetched: 1 row(s)
