> Project: Flink
> Issue Type: Bug
> Components: Deployment / Scripts
> Affects Versions: 1.19.1
> Reporter: Rob Young
> Priority: Minor
>
> To reproduce:
> 1. create a directory `mkdir my-flink-sql-gateway-project`
> 2. unpack a flink binary distribution inside that directory
> 3. run `./my-flink-sql-gateway-project/flink-1.19.1/bin/sql-client.sh
> Expected: the SQL console starts
> Actual: fails with stack trace:
> {code:java}
> Exception in thread "main" org.apache.flink.table.client.SqlClientException:
> Unexpected exception. This is a bug. Please consider filing an issue.
