Description

During testing multiple failures of the following sort are reported:

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)
        at org.apache.hadoop.mapred.gridmix.DummyResourceCalculatorPlugin.<init>(DummyResourceCalculatorPlugin.java:32)
        at org.apache.hadoop.mapred.gridmix.TestGridmixMemoryEmulation.testTotalHeapUsageEmulatorPlugin(TestGridmixMemoryEmulation.java:131)

This is because there is no SysInfo subclass for Solaris, from SysInfo.java

  public static SysInfo newInstance() {
    if (Shell.LINUX) {
      return new SysInfoLinux();
    }
    if (Shell.WINDOWS) {
      return new SysInfoWindows();
    }
    throw new UnsupportedOperationException("Could not determine OS");
  }

An implementation of SysInfoSolaris needs to be written and plumbed in to SysInfo.
