Cloudera Manager cannot kill queries

New Contributor

Hi all

 

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,

 

Lorenzo
