Subject [jira] [Created] (HDFS-3404) Make putImage in GetImageServlet infer remote address to fetch from
Date Thu, 10 May 2012 22:36:49 GMT
Aaron T. Myers created HDFS-3404:
------------------------------------

             Summary: Make putImage in GetImageServlet infer remote address to fetch from
                 Key: HDFS-3404
                 URL: https://issues.apache.org/jira/browse/HDFS-3404
             Project: Hadoop HDFS
          Issue Type: Improvement
    Affects Versions: 2.0.0
            Reporter: Aaron T. Myers
            Assignee: Aaron T. Myers


As it stands, daemons which perform checkpointing must determine their own address on which
they can be reached, so that the NN which they checkpoint against knows what address to fetch
a merged fsimage from. This causes problems if, for example, the daemon performing checkpointing
binds to 0.0.0.0, and thus can't be sure of what address the NN can reach it at.
