Jitendra Nath Pandey commented on HDFS-4794:
--------------------------------------------
Binoy,
JspHelper.namenodeAddr is a public static variable, which may be used in many
places, changing that might break something else. Note that jsp files could
also be referencing it where corresponding java files are auto-generated.
A safer approach is to leave this variable as it is and introduce another
variable like namenodeRpcAddr and use that other variable from the servlets
that are responsible for this error. Does that make sense?
If you are confident that it is not being used anywhere then we could consider
changing it into a private variable.
