Subject [jira] [Updated] (HDFS-5260) Merge zero-copy memory-mapped HDFS client reads to trunk and branch-2.
Date Thu, 26 Sep 2013 20:36:04 GMT

     [ https://issues.apache.org/jira/browse/HDFS-5260?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Chris Nauroth updated HDFS-5260:
--------------------------------

    Attachment: HDFS-5260.2.patch

Here is a new merge patch that also incorporates HDFS-5266 to correct the Findbugs warning
and Javadoc warning.

We're still going to have new javac warnings due to use of internal Sun APIs for {{munmap}}.
 We don't have a way to suppress those.
