> For the following query:
> select A.host as host1,B.host as host from `hosts` A  join host2 B on B.hostid=A.hostid;
> A.host and B.host are columns that have same name, but come from different tables, and have a different alias name. But looks like Avro conversion is ignoring the alias and just looking at the column name. This causes the query to fail with this error
> Duplicate Field Name in any.data.hosts ; name type UNION pos:1 and name type UNION pos:0.
> I have attached a screenshot for the same.
