             Summary: select a || b from ... fails while select cast(a as varchar) || cast(b
as varchar) from ...
                 Key: DRILL-2008
                 URL: https://issues.apache.org/jira/browse/DRILL-2008
             Project: Apache Drill
          Issue Type: Bug
          Components: Query Planning & Optimization
            Reporter: Sean Hsuan-Yi Chu
            Assignee: Jinfeng Ni

The first query would fail at planning by optiq/calcite. 

For example,
select n_name || n_name from cp.`tpch/nation.parquet`;
org.apache.drill.exec.rpc.RpcException: Query failed: Unexpected exception during fragment
initialization: null
