Daniel Templeton commented on YARN-6612:
----------------------------------------

Thanks, [~yufeigu].

bq. Would it be easier to understand if changing {{calculateShares()}} to {{calculateShareUsages()}}?

Not really?  Maybe I'm missing your point.

bq. What if weight is 0?

Interesting point!  Not a new issue, though.  I'll have a look to see why it's never bitten
us so far and whether we should fix it here.

bq. It doesn't need weight while calculating min share.

Also not a new issue.  That's the way it was calculated before.  Yeah, it looks wrong to me,
too.  [~kasha], any insights?

bq. Would it make more sense if we sort it by dominant min share which is minShare/cluster?

Also not a new issue.  I'm just trying to preserve the existing semantics.

I'll address the other issues and the unit tests in a new patch shortly.
