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')
Seems to be an issue for Hive>2.3+
Also known in Trino and fixed there - trinodb/trino#951
