Hi,   I'm trying to find out why I can't see any Impala query in Cloudera Manager. I have Cloudera Manager and 3 different clusters running Impala.

Hi,   Recently I was trying to add new hosts to my cluster. I add role to new host but Cloudera didn't create config files nor directories on datanode host.
