[jira] Commented: (HADOOP-5010) Replace HFTP/HSFTP with plain HTTP/HTTPS

["Doug Cutting (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/HADOOP-5010?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12663047#action_12663047 ] 

Doug Cutting commented on HADOOP-5010:
--------------------------------------

> simply offer standard HTTP and HTTPS

HFTP and HSFTP are just internal naming schemes, a way to encode HDFS file names but indicate that a different mechanism should be used to access them.

> That would allow non-HDFS-specific clients, as well as using various standard HTTP infrastructure, such as load balancers, etc.

We already use HTTP and HTTPS as the transport for HFTP and HSFTP.  So maybe all we need is better documentation of what's passed over HTTP?

> Recently, we've been talking about implementing an HDFS proxy (HADOOP-4575) which would be a secure way to make HFTP/HSFTP available. In so doing, we may even remove HFTP/HSFTP from being offered on the HDFS itself (that's another discussion).
> In the case of the HDFS proxy, does it make sense to do away with the artificial HFTP/HSFTP protocols, and instead simply offer standard HTTP and HTTPS? That would allow non-HDFS-specific clients, as well as using various standard HTTP infrastructure, such as load balancers, etc.
> NB, to the best of my knowledge, HFTP is only documented on the [distcp|http://hadoop.apache.org/core/docs/current/distcp.html] page, and HSFTP is not documented at all?
