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

             Summary: Error message not clear when we try to apply flatten on a non-repeated
column
                 Key: DRILL-2182
                 URL: https://issues.apache.org/jira/browse/DRILL-2182
             Project: Apache Drill
          Issue Type: Bug
          Components: Functions - Drill
            Reporter: Rahul Challapalli
            Assignee: Daniel Barclay (Drill/MapR)


git.commit.id.abbrev=c54bd6a

When we apply flatten on an integer column, the error message is obscure
{code}
0: jdbc:drill:schema=dfs_eea> select flatten(uid) from `data1.json`;
Query failed: RemoteRpcException: Failure while running fragment., org.apache.drill.exec.vector.NullableBigIntVector
cannot be cast to org.apache.drill.exec.vector.RepeatedVector [ 1a8a5802-d67b-4a86-82ff-098d997f696a
on qa-node191.qa.lab:31010 ]
[ 1a8a5802-d67b-4a86-82ff-098d997f696a on qa-node191.qa.lab:31010 ]


Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}

Below is the case for a map. This is an improvement from the above case. However I am not
sure whether user's understand what a repeated type is
{code}
0: jdbc:drill:schema=dfs_eea> select flatten(map) from `data1.json`;
Query failed: RemoteRpcException: Failure while running fragment., Trying to flatten a non-repeated
filed. [ 9c80ff81-59eb-4a14-9359-a639f03763ed on qa-node191.qa.lab:31010 ]
[ 9c80ff81-59eb-4a14-9359-a639f03763ed on qa-node191.qa.lab:31010 ]


Error: exception while executing query: Failure while executing query. (state=,code=0)
{code}
