----------------------------------------
Would https://impala.apache.org/docs/build/html/topics/impala_load_data.html
suffer from the same issue ?
> Data is being inserted even though an INSERT INTO query fails

> Key: IMPALA-11014
> URL: https://issues.apache.org/jira/browse/IMPALA-11014
> Project: IMPALA
> Issue Type: Bug
> Reporter: Tsvetomir Palashki
> Priority: Major
> Attachments: profile.txt
>
>
> We are executing an INSERT INTO query against Impala. In rare cases this
> query fails with the following error:
> {code:java}
> MetaException: Object with id "" is managed by a different persistence
> manager {code}
> Even though there is an error, the data is inserted into the table. This is
> particularly problematic due to our error handling logic, which refreshes the
> table metadata and retries the query, which causes data duplication.
> I am aware that this bug might be fixed in one of the newer Impala versions,
> but at this point, we are unable to upgrade.
> Can you suggest a workaround for this? Is it safe to assume that the data is
> always inserted when this particular error happens? Can we rely on the
> rows_inserted and rows_produced fields of the query in order to make
> assumptions about what data is inserted?
> The exact version of our Impala is:
> {code:java}
> impalad version 3.2.0-cdh6.3.2 RELEASE (build
> 1bb9836227301b839a32c6bc230e35439d5984ac) Built on Fri Nov 8 07:22:06 PST
> 2019 {code}
