> I configured Apache drill and connected to Mongo and created some nice 
> queries.
> This is a query that works fine - just a proof that the environment is 
> configured.
> SELECT interactionDateTime FROM interactionrecord limit 5;
> { "$date" : "2015-03-05T00:08:10.753Z"}
> { "$date" : "2015-03-05T00:08:10.794Z"}
> { "$date" : "2015-03-05T00:08:10.803Z"}
> { "$date" : "2015-03-05T00:08:35.180Z"}
> { "$date" : "2015-03-05T00:08:35.180Z"}
> This simple query fails regardless of upper or lower case of function name. 
> Similarly fail other queries that use other data time functions. This one 
> seemed the simplest...
> SELECT CURRENT_DATE FROM interactionrecord limit 5;
> Query failed to execute. Execute Query failed. 
> Error type: Odbc error. Odbc operation attempted: SQLExecDirect. [S1000:1040: 
> on HSTMT] [MapR][Drill] (1040) Drill failed to execute the query: SELECT 
> CURRENT_DATE FROM interactionrecord limit 5
> [30024]Query execution error. Details:[ 
> Query stopped., Failure while trying to materialize incoming schema. Errors:
