It says CHAR is supported and LIST, MAP, STRUCT, TIMESTAMP (Unix Epoch format), UNION are not supported.
While querying a table with char datatype field, Drill client says:
Unsupported Hive data type CHAR.
Following Hive data types are supported in Drill INFORMATION_SCHEMA:
BOOLEAN, BYTE, SHORT, INT, LONG, FLOAT, DOUBLE, DATE, TIMESTAMP,
BINARY, DECIMAL, STRING, VARCHAR, LIST, MAP, STRUCT and UNION
This is really confusing. Please look into this.
