---------------------------------------------

             Summary: CAST to MAP yields internal "use createMultisetType() instead" error
                 Key: DRILL-2660
                 URL: https://issues.apache.org/jira/browse/DRILL-2660
             Project: Apache Drill
          Issue Type: Bug
            Reporter: Daniel Barclay (Drill)
         Attachments: Temp1.csv, Temp2.csv

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.
