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

             Summary: Derby does not support CLOB comparisons
                 Key: HIVE-21614
                 URL: https://issues.apache.org/jira/browse/HIVE-21614
             Project: Hive
          Issue Type: Bug
          Components: Metastore
    Affects Versions: 2.3.4, 3.0.0
            Reporter: Vlad Rozov


HiveMetaStoreClient.listTableNamesByFilter() with non empty filter causes exception with Derby DB:
{noformat}
Caused by: ERROR 42818: Comparisons between 'CLOB (UCS_BASIC)' and 'CLOB (UCS_BASIC)' are not supported. Types must be comparable. String types must also have matching collation. If collation does not match, a possible solution is to cast operands to force them to the default collation (e.g. SELECT tablename FROM sys.systables WHERE CAST(tablename AS VARCHAR(128)) = 'T1')
