Description

Calling the Path.suffix method on root raises a NullPointerException. Tested with hadoop-client-api 3.3.2

Scenario:

import org.apache.hadoop.fs.*

Path root = new Path("/")
root.getParent == null  // true
root.suffix("bar")  // NPE is raised

Stack:

	at org.apache.hadoop.fs.Path.<init>(Path.java:104)
