Suresh Srinivas commented on HDFS-4945:
---------------------------------------
Some comments:
# I have hardtime understanding "two NameNodes have to share a highly-reliable
sophisticated storage" - what is sophisticated about having an NFS mount point,
currently used for storing FSImage?
# For the sake of completeness please include information related federation
which can support multiple namenodes in a cluster
# Please add a design document.
# Do you have a prototype working?
Why is Affects Version/s set to HDFS-1623?
