I'm not able to kill Yarn applicantions or Impala queries from user interface in Cloudera Manager(5.4.0).
When I try to kill a query in Impala, I receice "Error communicating with the Impala Daemon."
In Yarn instead I receive apparently no errors, but the query is not killed.
Which type of logs can I investigate? Which user is executing the kill command? (cloudera-scm???)
I know that exist a yarn shell command for killing application, but is it available an equivalent one for Impala?
My cluster is kerberized.
Thanks in advance,
