Update:
I figured out that error happens only of the SQL contains JOIN of any kind. If
there are no JOINs, everything works fine.
Any help?
Hello,
I am trying to use CloseableIterator, but next() operation reliably generates
the following error:
java.util.concurrent.ExecutionException: org.apache.flink.util.FlinkException:
Coordinator of operator 4596fb32cad14208ec80c1cae8623e11 does not exist or the
job vertex this operator belongs to is not initialized.

Code that generates exception:
String snapshotSQl = <Some hardcoded SQL string>
org.apache.flink.table.api.Table snapshotTable = tableEnv.sqlQuery(snapshotSQl);
snapshotTable.execute().collect().next();
Any help will be greatly appreciated.
