------------------------------------
Assignee: Matt Burgess
> Executesql convert to avrò fails when a mysql query returns two columns with
> the same name even with different aliases
> ----------------------------------------------------------------------------------------------------------------------
>
> Key: NIFI-3064
> URL: https://issues.apache.org/jira/browse/NIFI-3064
> Project: Apache NiFi
> Issue Type: Bug
> Affects Versions: 1.0.0, 0.7.0, 0.6.1
> Reporter: Karthik Narayanan
> Assignee: Matt Burgess
>
> Customer came with some issues in executing query using executesql. He
> thought the error was due to biting field in the query. But, upon research i
> was able to reproduce the error when i tried this particular query
> select A.host as host1,B.host as host from `hosts` A join host2 B on
> B.hostid=A.hostid;
> in the above query 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.
