Subject [jira] [Commented] (HDFS-1623) High Availability Framework for HDFS NN
Date Wed, 14 Mar 2012 21:32:46 GMT

    [ https://issues.apache.org/jira/browse/HDFS-1623?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13229647#comment-13229647
] 

Todd Lipcon commented on HDFS-1623:
-----------------------------------

bq. From experience, I suspect getting the code for IP based automated failover working in
a multi-SBN approach to where the community is ready to see it as a stable codebase/release
will probably take some more investment. 

yep, I didn't mean to indicate that the whole project is trivial. Just that the majority of
issues we had to solve for the current failover implementation also apply to the IP-failover
implementation. The remaining work to do IP-failover is much smaller than the amount already
behind us.
