Konstantin Shvachko commented on HADOOP-5097:
---------------------------------------------
# Remove comment in FSNamesystem
/** NameNode RPC address */
# I do not very much like that you add JspHelper as a NameNode members. I
understand the intention is not to instantiate objects on the web UI, but may
be we should rather consider making most of the methods / fields of JspHelper
static instead of constructing the object. In any case it is better not to
introduce helper variables in NamNode and DataNode.
> Remove static variable JspHelper.fsn
