-------------------------------------------
Summary: 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
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
