Description

When catalogd fails to start, the error message is

Starting Catalog Service logging to /home/ubuntu/Impala/logs/cluster/catalogd.INFO
Error starting cluster: Unable to start catalogd. Check log or file permissions for more details.

But sometimes that log shows no useful information and the other message doesn't explain which file permissions to check. An example log without much information:

Changing the ownership of all the files in the home directory of the user did not alleviate the problem.
