Hi Ajay, As I mentioned before in the previous post: Hue will hold the query handler open so that it can do paginations, and it will only kill the handler after user navigates away from the impala page. If user stays on the page, the handler will be kept open and the query is considered as in flight. This is intended and part of design. If you do not want it to be open for long time, you need to set the idle_session_timeout at Impala level. Cheers Eric
