Subject [jira] [Created] (HDFS-10951) libhdfs++: FileHandle should handle DN failure internally
Date Mon, 03 Oct 2016 21:52:20 GMT
James Clampffer created HDFS-10951:

             Summary: libhdfs++: FileHandle should handle DN failure internally
                 Key: HDFS-10951
                 URL: https://issues.apache.org/jira/browse/HDFS-10951
             Project: Hadoop HDFS
          Issue Type: Sub-task
            Reporter: James Clampffer
            Assignee: James Clampffer
            Priority: Minor

Currently if a read hits a bad DN it will add it to the DN exclusion set and return an error.
 It'd be nice if it'd exhaust attempts to all replica locations before returning an error
so client applications don't have to attempt to figure out the difference between "File not
found" and "DN not responsive, go try a different DN".
