UnsupportedOperationException: Unimplemented type: UNION

[Kartik Bhatia <KB...@scif.com>]

Hi,
I am getting the following error while I try to run avro file.

0: jdbc:drill:zk=local> SELECT * FROM dfs.`C:\Users\kb97407\Downloads\apache-dri
ll-1.1.0.tar\apache-drill-1.1.0\apache-drill-1.1.0\sample-data\sample1.avro` LIMIT 3;
Error: SYSTEM ERROR: UnsupportedOperationException: Unimplemented type: UNION

Fragment 0:0

ate=,code=0)

However according to drill documentation see below (it says feature is supported)

SQL UNION Improvements

We've enhanced support for SQL UNION functionality. Drill now supports both UNION and UNION ALL capabilities. We've also improved the query optimizer to better optimize plans that include the UNION clause.
