[jira] [Created] (HDFS-2839) Nameservice id in file uri could cause issues

Nameservice id in file uri could cause issues
---------------------------------------------

                 Key: HDFS-2839
                 URL: https://issues.apache.org/jira/browse/HDFS-2839
             Project: Hadoop HDFS
          Issue Type: Sub-task
    Affects Versions: HA branch (HDFS-1623)
            Reporter: Jitendra Nath Pandey
            Assignee: Jitendra Nath Pandey


There might be two issues with having a nameservice id in fully qualified paths of the files.
1) Some applications might be storing the fully qualified paths. They will have hostnames from pre-ha installations, and they might break after the failover.
2) The fully qualified path from an ha cluster, won't be usable from a different cluster that doesn't know about that particular namespace id.
