Todd Lipcon commented on HDFS-2720:
-----------------------------------
Small nits:
{code}
+ // Now format 1st NN and copy the storage dirs to remaining all.
{code}
"to remaining all" seems like a typo. "copy the storage directory from that
node to the others." would be better. Also I think it's easier to read "first"
than "1st"
----
{code}
+ //Start all Namenodes
{code}
add space after {{//}}
----
- The change to remove setRpcEngine looks unrelated - that should get cleaned
up in trunk so it doesn't present a merge issue in the branch.
