Subject [jira] [Commented] (HDFS-5570) Deprecate hftp / hsftp and replace them with webhdfs / swebhdfs
Date Thu, 27 Mar 2014 23:15:19 GMT

    [ https://issues.apache.org/jira/browse/HDFS-5570?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13950106#comment-13950106

Jing Zhao commented on HDFS-5570:

Also, for the webUrl part, now can we generalize it to "http url of webhdfs" and "fs uri"?
I think the former should be necessary (the current patch does not support it). For later
if hdfs/webhdsf/swebhdfs scheme is provided we can even support HA (but this also requires
extra information in the configuration). We should also document it and include it in the
tool usage description.

> Currently hftp / hsftp only provide a strict subset of functionality that webhdfs / swebhdfs
offer. Notably, hftp / hsftp do not support writes and HA namenodes. Maintaining two piece
of code with similar functionality introduce unnecessary work.
> Webhdfs has been around since Hadoop 1.0 therefore moving forward with webhdfs does not
seem to cause any significant migration issues.
> This jira proposes to deprecate hftp / hsftp in branch-2 and remove them in trunk.
