Guangyuan Feng updated KYLIN-5546:
----------------------------------
Description:
h2. Issues
Currently, Kylin has no open APIs to cancel/kill the asynchronous running
query, users have to dig into the log and find out the Spark process, then to
kill the process manually.
Without the entrypoint to kill the running asynchronous queries, the server
will lose control of resources, finally enter into a unstable state.
So I think it's great for Kylin to supply such an open API, to cancel/kill the
asynchronous submitted queries.
h2. Proposal changes
Supply a *DELETE* REST API {{{}/async_query/stop/{query_id:.+{}}}} to kill the
submitted asynchronous query by the {{{}query id{}}}.
