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,

Hi all, I'm trying to backup fsimage on a secure cluster with the -fetchImage command. I want to execute it without using hdfs user, but with an administrative user(adminUser) which belongs to hdfs' supergroup ( dfs.permissions.supergroup , dfs.permissions.superusergroup = supergroup) adminUser is local to the machine. When I try the command: kinit adminUser hdfs dfsadmin -fetchImage /backup_folder I obtain the following error: 15/05/11 16:38:42 WARN security.UserGroupInformation: PriviledgedActionException as:adminUser@<DOMAIN.LOCAL> (auth:KERBEROS) cause:org.apache.hadoop.hdfs.server.namenode.TransferFsImage$HttpGetFailedException: Image transfer servlet at http://<namenode>:50070/imagetransfer?getimage=1&txid=latest failed with status code 403 Response message: Only Namenode, Secondary Namenode, and administrators may access this servlet fetchImage: Image transfer servlet at http://<namenode>:50070/imagetransfer?getimage=1&txid=latest failed with status code 403 Response message: Only Namenode, Secondary Namenode, and administrators may access this servlet However, others dfsadmin commands (like -report) work fine with adminUser. Thanks in advance
