Sean Busbey commented on HBASE-22475:
-------------------------------------
This is fallout from the combination of our Jackson upgrade in HBase 2 and
updating our Hadoop 2 version to 2.8. we had a similar CNFE in a rest module
test. Essentially it depends on if some static methods in Configuration get
touched.
Does the Hadoop 2 we bundle include Jackson jars? Is the failed test relying on
our packages Hadoop or the Hadoop executable?
