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

             Summary: Empty table during a join operation with a non empty 
table produces cast exception 
                 Key: DRILL-5851
                 URL: https://issues.apache.org/jira/browse/DRILL-5851
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Relational Operators
    Affects Versions: 1.11.0
            Reporter: Hanumath Rao Maduri
            Assignee: Hanumath Rao Maduri


Hash Join operation on tables with one table empty and the other non empty 
throws an exception 
{code} 
Error: SYSTEM ERROR: DrillRuntimeException: Join only supports implicit casts 
between 1. Numeric data
 2. Varchar, Varbinary data 3. Date, Timestamp data Left type: VARCHAR, Right 
type: INT. Add explicit casts to avoid this error
{code}

Here is an example query with which it is reproducible.

{code}
select * from cp.`sample-data/nation.parquet` nation left outer join 
dfs.tmp.`2.csv` as two on two.a = nation.`N_COMMENT`;
{code}

the contents of 2.csv is empty (i.e not even header info).
