Subject current direction in namenode HA
Date Tue, 04 Sep 2012 22:37:06 GMT
Hello devs,

I am trying to understand the current state / direction of  namenode
HA implementation.

For using shared directory, I see the following options
(from http://www.cloudera.com/blog/2012/03/high-availability-for-the-hadoop-distributed-file-system-hdfs/
  and  https://issues.apache.org/jira/browse/HDFS-3278)

1) rely on external HA filer
2) multiple edit directories
3) book keeper
4) keep edits in HDFS / quorum based

is there going to be an 'official / supported' method, or it is going
to be a configurable choice when setting up a cluster?

thanks
