I think there might be a compatibility break though its from Resources class
{quote}
LimitedPrivate only applicable for specified projects.. So i don't think its an
issue.
{code}
@InterfaceAudience.LimitedPrivate({"YARN", "MapReduce"})
@Unstable
{code}

So using Math.floor(value * 10^N) / 10^N where N could be 6 will help to
resolve the problem for now.
{quote}
The issue with solution mentioned is we are limiting the max value of
resource that can be configured for attributes to {{MAX VALUE / 10^N}} i
wouldn't prefer for these reasons.
IF you feel all the above can be ignored then i can go ahead and change.
