      Description

      When checking whether Impala has access to a path here:
      https://github.com/cloudera/Impala/blob/cdh5-trunk/fe/src/main/java/com/cloudera/impala/util/FsPermissionChecker.java#L273-L285

      we detect if ACLs are disabled by catching the exceptions thrown by the NN. Logging these exceptions locally (with heavy Impala load) can impact NN performance.
