Alan Burlison commented on HADOOP-12580:
----------------------------------------
I think that would work - AFAIK all the shell utilities that are used are POSIX
ones, although I'd have to check the command-line flags against POSIX to be
100% sure.

> During testing multiple failures of the following sort are reported:
> {code}
> java.lang.UnsupportedOperationException: Could not determine OS
> at org.apache.hadoop.util.SysInfo.newInstance(SysInfo.java:43)
> at
> org.apache.hadoop.yarn.util.ResourceCalculatorPlugin.<init>(ResourceCalculatorPlugin.java:41)

> This is because there is no SysInfo subclass for Solaris, from SysInfo.java
> {code}
> public static SysInfo newInstance() {
> if (Shell.LINUX) {
> return new SysInfoLinux();
> }
> if (Shell.WINDOWS) {
> return new SysInfoWindows();
