[jira] [Resolved] (HDFS-5221) hftp: does not work with HA NN configuration

     [ https://issues.apache.org/jira/browse/HDFS-5221?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Andrew Wang resolved HDFS-5221.
-------------------------------

    Resolution: Duplicate

Duping to HDFS-5123. Joep, it seems likely that one of your two approaches will be implemented (probably the first).

> When copying data between clusters of significant different version (say from Hadoop 1.x equivalent to Hadoop 2.x) we have to use hftp.
> When HA is configured, you have to point to a single (active) NN.
> Now, when the active NN becomes standby, the the hftp: addresses will fail.
