---------------------------------
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')
