Description

$ hbase org.apache.hadoop.hbase.thrift.HttpDoAsClient localhost 9095 hbase security=true
Exception in thread "main" java.util.NoSuchElementException
	at java.util.LinkedList$ListItr.next(LinkedList.java:890)
	at javax.security.auth.Subject$SecureSet$1.next(Subject.java:1056)
	at org.apache.hadoop.hbase.thrift.HttpDoAsClient.main(HttpDoAsClient.java:85)

When Subject cannot be retrieved (e.g. due to empty ticket cache), we shouldn't end up with NoSuchElementException.
Better error message should be given.
