File docs/topics/impala_known_issues.xml:

PS1, Line 146: from hostname command
I think the precise issue is that Impala must have the --hostname flag set to the FQDN. If
the user does not set --hostname explicitly to the FQDN, Impala will use gethostname() (not
the command 'hostname') to determine the value of the flag. If that call returns a non-FQ
DN, Kerberos will not work. 

If there's a problem with gethostname(), that can be detected by the user running 'hostname'
which calls the gethostname() system call.
