To retest a patch, you can cancel it and then resubmit it. If you do not cancel before resubmitting, Hive QA will ignore itThese two status changes are not necessary for a new patch that has a different filename, but if the filename stays the same then Hive QA ignores the patch after its first test unless you cancel and resubmit.
To prevent precommit testing, include the case-sensitive phrase NO PRECOMMIT TESTS in the Description section of the JIRA issue. You can remove it later as needed. For examples, see HIVE-5289, HIVE-7343, and HIVE-7375.
