Hanumath Rao Maduri created DRILL-5851:
------------------------------------------
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).
