> I don't know if data type name "MAP" is intended to be supported or not, but trying to use it in a CAST specification yields an internal error message "use createMultisetType() instead":
> 0: jdbc:drill:zk=local> CREATE OR REPLACE VIEW TempView AS SELECT CAST(columns AS MULTISET), columns FROM `dfs.tmp`.`dsbtemp/TempCsv`;
> Query failed: AssertionError: use createMultisetType() instead
> Error: exception while executing query: Failure while executing query. (state=,code=0)
> 0: jdbc:drill:zk=local> 
> The directory corresponding to `dfs.tmp`.`dsbtemp/TempCsv` contained the two attached CSV files.
