------------------------------------------

             Summary: some small DomainSocket fixes: avoid findbugs warning, change log level, etc.
                 Key: HDFS-4402
                 URL: https://issues.apache.org/jira/browse/HDFS-4402
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: Colin Patrick McCabe
            Priority: Minor


Some miscellaneous fixes:
* findbugs complains about a short-circuit operator in {{DomainSocket.java}} for some reason.  We don't need it (it doesn't help optimization since the expressions lack side-effects), so let's ditch it to avoid the findbugs warning.
* change the log level of one error message to warn
* BlockReaderLocal should use a BufferedInputStream to read the metadata file header, to avoid doing multiple small reads.
