Subject [jira] [Commented] (HDFS-2292) HA: HTTP fail-over
Date Wed, 01 Feb 2012 15:54:59 GMT

    [ https://issues.apache.org/jira/browse/HDFS-2292?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13197918#comment-13197918

Alejandro Abdelnur commented on HDFS-2292:

Do we have to address this as part of Hadoop? IMO this is more of a deployment issue, where
you could use a reverse proxy in between the redundant HTTP services and the clients. I think
that what we should address from Hadoop is making all its HTTP services redundant (dual headed).
For example httpfs could be deploy in multiple boxes and use a round robin DNS configuration.
