Tsuyoshi OZAWA commented on YARN-1472:
--------------------------------------
Thank you for reporting, [~shenhong]. IIUC, the code you pointed out is for
avoiding getting illegal property such as "hadoop.proxyuser..groups".
Configuration.getValByRegex(regex) only checks keys by using regular
expression, and it doesn't check its values.
