> HADOOP-7854 added synchronization to {{getCurrentUser}} due to {{ConcurrentModificationExceptions}}.
 This degrades NN call handler performance.
> The problem was not well understood at the time, but it's caused by a collision between
relogin and {{getCurrentUser}} due to a bug in {{Krb5LoginModule}}.  Avoiding the collision
will allow removal of the synchronization.
