Sunil G commented on YARN-7856:
-------------------------------
Thanks [~cheersyang]
Few comments.
1. {{equals}} could u pls check a case where one of getAttributePrefix may be
null. (we check both null scenario only now)
2. In {{validateNodeAttributes}} we could add some checks to avoid special
characters etc, correct? like alphanumerical string.
3. May be the number of attributes are smaller, however instead of calling
{{validateNodeAttributes}} with a set of attributes, we could validate each of
these attribute alone.

> NM needs to do proper validation about the attributes before sending them to
> RM, this includes
> # a valid prefix is presented
> # no duplicate entries
> # do not allow two attributes with same prefix/name but different types
> This could be an utility class that can be used on both RM/NM sides.
