Todd Lipcon commented on HDFS-2733:
-----------------------------------
- "In the event of an unplanned event" could be worded better
- The doc for dfs.federation.nameservices should indicate that, if federation
is also being used, that this would be a comma-separated list of nameservice
IDs (some of which may be HA and some of which might not be)
- I think the example nameservice ID should be something like "mycluster" or
"mynameservice" rather than "ha-nn-uri" -- it doubles as the URI but that's a
side effect rather than the important bit, I think.
- Add a "note" for dfs.namenode.http-address that https-address should be
configured on a secure cluster
- For the "shell" fencing method, should note that the address of the service
to be fenced will be inserted as the first argument
- "This is not yet implemented, and at present will always return success" --
if the NN is down it will return non-zero, right? So it still has some basic
use.
