RecordService config issues

When starting up record service, we still see two config issues:

• E0722 17:15:44.025209 26815 impala-server.cc:252] ERROR: short-circuit local reads is disabled because Impala cannot read or execute the parent directory of dfs.domain.socket.path
  ERROR: block location tracking is not properly enabled because
• dfs.client.file-block-storage-locations.timeout.millis is too low. It should be at least 10 seconds.

The first only happens on nodes without running DNs and we should fix the verification logic. The second is a config issue that we want to resolve. CM explicitly only generates the second config for Impala.
