Aaron T. Myers commented on HADOOP-8585:
----------------------------------------
bq. Wouldn't it have been easier to just suppress the warning as a false alarm?
That would certainly work, but it doesn't seem much easier to me. I also don't
see how the method used by this patch could possibly cause any problems, as it
changes the behavior back to what it was before the recently-committed
HDFS-3568, i.e. each invocation of newLoginContext will create a new
HadoopConfiguration object.
