      Description

      Please refer to these two links and correct one of them.

      http://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-hdfs/HdfsDesign.html

      The NameNode machine is a single point of failure for an HDFS cluster. If the NameNode machine fails, manual intervention is necessary. Currently, automatic restart and failover of the NameNode software to another machine is not supported.

      http://hadoop.apache.org/docs/r2.7.1/hadoop-project-dist/hadoop-hdfs/HDFSHighAvailabilityWithQJM.html

      The HDFS High Availability feature addresses the above problems by providing the option of running two redundant NameNodes in the same cluster in an Active/Passive configuration with a hot standby. This allows a fast failover to a new NameNode in the case that a machine crashes, or a graceful administrator-initiated failover for the purpose of planned maintenance.

      Please update hdfsDesign article with same facts to avoid confusion in Reader's mind..

        But we are not explicitly saying that Namenode is not single point of failure. Is it intended?

        Hi, Please deploy this patch as early as possible to avoid confusion in reader's mind. Without this patch, readers of HDFS design article will think that HDFS name node is single point of failure in the system even though it's not a single point of failure.

        The process is relatively simple:

        a) contributor submits a patch
        b) QA bot does static analysis to cover some of the review work
        c) committer reads through patch after QA bot says it is good
        d) committer gives a +1 if it is good, -1 or general feedback if it has issues
        e) if good, committer commits against source tree for releases that the committer feels it should be in, etc
        f) patch shows up in next release that contains that patch

        So even if this were to get committed right this second, it likely won't show up on the website for a very long time. Also keep in mind that there are literally hundreds of JIRAs in patch available state. It can take a while for someone to get to it.

        I think the fix is very important because users probably read this document at first and may misunderstand that NameNode is SPOF. Cherry-picked this to branch-2.7.

        How to know which all unit tests have been failed

        Failed tests are listed in the following link, but the link will be expired in a few weeks. (This link is expired.)

        FAILURE: Integrated in Hadoop-Hdfs-trunk #2567 (See https://builds.apache.org/job/Hadoop-Hdfs-trunk/2567/)

        and how to address them?

        Usually the test failures have been already reported in jira. You can search the issue and fix the test. If you can't find the issue, you can create a issue to fix the the failing test.

        Is there a way to get it deployed without addressing these failures?

        The tests are executed after the patch is committed, so the patch is applied to trunk/branch-2/... if the tests fail or not.

        It is deployed when Apache Hadoop 2.7.3 or higher version is released. I think Hadoop 2.7.3 will be released soon. Stay tuned!
