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 Sujee http://sujee.net
