> Originally found in {{TestDFSAdminWithHA#tearDown}} where System.out.flush() throws an
NPE. 
> The cause is that if for any reason {{setUpHaCluster}} fails before storing {{System.out}}
and {{System.err}} as member variables {{originOut}} and {{originErr}}, then in {{tearDown}}
{{System.out}} and {{System.err}} are set to null. This could cause all following tests to
fail when calling {{flush}}.
> This jira tries to fix all similar occurrences of this issue
