Description

https://builds.apache.org/job/Hadoop-Common-trunk/2053/testReport/junit/org.apache.hadoop.security.authentication.util/TestZKSignerSecretProvider/testMultipleInit/

Error Message

Stacktrace

java.lang.AssertionError: expected null, but was:<[B@142bad79>

I think the failure was introduced after HADOOP-12181

This is likely where the root cause is:
