Restart Impala fatal error

Restart Impala fatal error

New Contributor

I tried to restart Impala in Cloudera Manager and got fatal error. 

 

Below is the log. My HDFS system is up an running as I confirmed. How to troubleshoot this?

Re: Restart Impala fatal error

Master Collaborator

I would go you your impala service in CM, then click Configuration->View & Edit and then type "myenvFileSystem" in the keywords field.  It seems that you've attempted to configure some custom class in your Impala configs that is not present on your systems?
