If we create HiveConnectionPool controller service outside of any of the process groups, they do not appear in the dropdown of PutHiveQL to be selected, under any of the process groups. The only option is to create a separate HiveConnectionPool controller service within the process group. Is this expected behavior, if so what are the benefits?
On another issue, I noticed if we copy the PutHiveQL processor from process group to another, even if the associated HiveConnectionPool controller service is enabled, when the processor is run it throws the below error.
PutHiveQL[id=01581169-e0a4-10e0-eab4-0f04f9d74f16] PutHiveQL[id=01581169-e0a4-10e0-eab4-0f04f9d74f16] failed to process session due to java.lang.reflect.UndeclaredThrowableException: java.lang.reflect.UndeclaredThrowableException
