Zhijie Shen resolved YARN-2282.
-------------------------------

    Resolution: Invalid

Please ask questions via hadoop user mailing list: user\@hadoop.apache.org

To this question:

Which scheduler do you use? Would you please check you configuration? Make sure you're using
DominantResourceCalculator instead of DefaultResourceCalculator. Otherwise, when normalizing
a request, the vcore field will be reset to 1.
