Are you sure you have the correct version number? the lines in your stack trace don't line up with the Apache Accumulo 1.6.1 release. It looks like they are from an HDP release of Accumulo, but we'll need to know which one specifically.
Can you quickly confirm that the instance secret in the accumulo-site.xml file used by the GC process is the same as your other roles? Does this happen across GC instances, or just one in particular?
