[jira] [Created] (FLINK-24214) A submit job failure crashes the sql
client
Francesco Guardiani created FLINK-24214:
-------------------------------------------
Summary: A submit job failure crashes the sql client
Key: FLINK-24214
URL: https://issues.apache.org/jira/browse/FLINK-24214
Project: Flink
Issue Type: Bug
Components: Table SQL / Client
Affects Versions: 1.13.2
Environment: Flink 1.13.2
Ubuntu 21.04
Java 8
Reporter: Francesco Guardiani
I've noticed that when executing a valid query, in case there is a "bad" error when submitting it to the flink cluster, the client is going to crash, with a misleading beginning of the stacktrace. For example:
{code:java}

Shutting down the session...
done.
{code}
Or another example is in this issue: https://issues.apache.org/jira/browse/FLINK-22188
Shouldn't we catch these exceptions and nicely report them, without crashing the client? For example, the exception could be written to stdout and to a log, without crashing the client, thus waiting for the next input query.
Also the initial lines of the stacktrace are misleading:
{code}
Exception in thread "main" org.apache.flink.table.client.SqlClientException: Unexpected exception. This is a bug. Please consider filing an issue.
{code}
While it's clearly a misconfiguration from my side of the connector.
What do you think about it?
