I have some questions about the running queries in Impala UI. ( port:25000 )
There are some queries hanging in `in flight `
Those queries seems dead.
I tried to remove it by clicking 'Cancel' button, but I just saw the msg, "Error: Query not yet running"
Is there any other way to remove those queries from `in flight` status without restarting impala-server?
Is there any way ( or Impala-server API ) to retrieve all "Completed Queries" at node level?
What version of impala are you using? Would you be able to share the impalad.INFO log file when the problem occurs?
Regarding question #2: The web UI is the only way to access the query archive from the impalad itself. You can increase the number of queries archived using the --query_log_size, or keep track of all queries by setting the option to -1 (note however, that the archive is kept in memory and so if it's set to -1, the memory usage will continue to grow).
