> - Created extra (db, tbl, part) index on HIVE_LOCKS table;
> - Replaced inner select under checkLocks using multiple IN statements with

> generated query looks like :
> {code}
> SELECT LS.* FROM (
> SELECT HL_LOCK_EXT_ID, HL_LOCK_INT_ID, HL_DB, HL_TABLE, HL_PARTITION,
> HL_LOCK_STATE, HL_LOCK_TYPE, HL_TXNID FROM HIVE_LOCKS
> WHERE HL_LOCK_EXT_ID < 12143) LS
> LEFT JOIN (
> SELECT HL_DB, HL_TABLE, HL_PARTITION FROM HIVE_LOCKS WHERE HL_LOCK_EXT_ID
> = 12143) LBC
> ON LS.HL_DB = LBC.HL_DB AND LS.HL_TABLE = LBC.HL_TABLE AND LS.HL_PARTITION =
> LBC.HL_PARTITION
> WHERE (LS.HL_TABLE IS NULL OR LBC.HL_DB IS NOT NULL)
> AND (LS.HL_PARTITION IS NULL OR LBC.HL_DB IS NOT NULL)
> {code}
