Amir Sanjar commented on HBASE-7910:
------------------------------------
Removing reflection from UserGroupInformation (IBM JVM vs SUN JVM login
section) will break hadoop on any platforms that SUN/Oracle JVM is not
supported - i.e. POWERFPC and S390x. The real solution will be to develop
hadoop security component that is independent of platform and JVM vendor.
> Dont use reflection for security

> security.User class uses reflection so that HBase can work with older
> Hadoop's not having security. Now that we require 1.x, or 0.23 or 2.x, all
> Hadoop versions have security code. We can get rid of most of the User class.
