> I tried to register 21 jars simultaneously (property 'udf.retry-attempts' =
> 30) and not all jars were registered. As I see in output, all function were
> registered and /staging directory was empty, but not all of jars were moved
> into /registry directory.
> For example, after simultaneously registration I saw "The following UDFs in
> jar test-1.1.jar have been registered: [test1(VARCHAR-REQUIRED)" message, but
> this jar was not in /registry directory. When I tried to run function test1,
> I got this error: "Error: SYSTEM ERROR: SqlValidatorException: No match found
> for function signature test1(<CHARACTER>)". And when I tried to reregister
> this jar, I got "Jar with test-1.1.jar name has been already registered".
