So if you want to query __time column in druid datasource - you will see KeyError

  File "/usr/lib/python3.7/site-packages/pyhive/hive.py", line 321, in description
    type_code = ttypes.TTypeId._VALUES_TO_NAMES[type_id]
KeyError: 22

Supported types are:

{0: 'BOOLEAN_TYPE', 1: 'TINYINT_TYPE', 2: 'SMALLINT_TYPE', 3: 'INT_TYPE', 4: 'BIGINT_TYPE', 5: 'FLOAT_TYPE', 6: 'DOUBLE_TYPE', 7: 'STRING_TYPE', 8: 'TIMESTAMP_TYPE', 9: 'BINARY_TYPE', 10: 'ARRAY_TYPE', 11: 'MAP_TYPE', 12: 'STRUCT_TYPE', 13: 'UNION_TYPE', 14: 'USER_DEFINED_TYPE', 15: 'DECIMAL_TYPE', 16: 'NULL_TYPE', 17: 'DATE_TYPE', 18: 'VARCHAR_TYPE', 19: 'CHAR_TYPE', 20: 'INTERVAL_YEAR_MONTH_TYPE', 21: 'INTERVAL_DAY_TIME_TYPE'}

Could somebody help me with fixing non existing type for time column?
