Colin Patrick McCabe created HDFS-4402:
------------------------------------------
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.
