Balazs Jeszenszky resolved IMPALA-7562.
---------------------------------------
Resolution: Not A Bug
You would probably have to recreate your JDBC connections and implement retry
logic within your app.
Resolving since Impala itself is working fine, things recover once you restart
the web application.

> I encountered a very strange problem. Spring boot configured impala JDBC
> query. Under normal circumstances, all SQL queries are normal, and the
> statement has no problem.However, after I restart the impala service, this
> exception will be reported, or the same error code will be reported for all
> SQL queries. After I have to restart my spring boot web service, all the
> queries will be normal again, as I have tried many times.I looked through the
> server logs and found that I did not seem to have received the request.But
> why is this problem so low?Is it driven?My impala is three nodes built under
> CDH.
> I really can not find out the reason, please help to look.thank you
