> Found the following NPE thrown in UGI tgt renewer. The NPE was thrown within an exception
handler so the original exception was hidden, though it's likely caused by expired tgt.

> 18/07/02 10:30:57 ERROR util.SparkUncaughtExceptionHandler: Uncaught exception in thread
Thread[TGT Renewer for foo@EXAMPLE.COM,5,main]

>         at java.lang.Thread.run(Thread.java:748){noformat}
> Suspect it's related to [https://bugs.openjdk.java.net/browse/JDK-8154889].
