------------------------------------

             Summary: The HiveMetastore.exchange_partitions method throws FileNotFoundException if the given partition doesn't exist in the source table
                 Key: HIVE-18697
                 URL: https://issues.apache.org/jira/browse/HIVE-18697
             Project: Hive
          Issue Type: Bug
          Components: Metastore
            Reporter: Marta Kuczora
            Assignee: Marta Kuczora


If calling the HiveMetastore.exchange_partitions method with a non-existing partition, a FileNotFoundException will occur. Since the partitions of the source table are fetched
{code:java}
List<Partition> partitionsToExchange = get_partitions_ps(sourceDbName, sourceTableName,
          partVals, (short)-1);
{code}
this use case could be handled better by checking if the partitionsToExchange list is empty and if it is, throw a MetaException with a proper error message that no partition exists for the source table with the given values.

See the testExchangePartitionsNoPartExists test case in the TestExchangePartitions test.
