Subject [jira] [Commented] (HDFS-1973) HA: HDFS clients must handle namenode failover and switch over to the new active namenode.
Date Fri, 26 Aug 2011 02:26:29 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1973?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13091525#comment-13091525

Eli Collins commented on HDFS-1973:
-----------------------------------

@atm - mind filing a separate jira for HTTP fail-over? In some cases we may be able to define
away the problem. Eg now that 1073 is in we could modify the 2NN to not have to fetch files
via http (at least when using shared storage).

> During failover, a client must detect the current active namenode failure and switch
over to the new active namenode. The switch over might make use of IP failover or some thing
more elaborate such as zookeeper to discover the new active.
