> Experienced several small problems while testing accumulo on cluster using random walk testing:
> * zookeeper lock was not removed for a hung tablet server (see ACCUMULO-16)
> * spurious message about a merge not in progress
> * NPE during a trivial merge
> * balancer would not run when a tablet server was unresponsive
> * NPE reading permissions from a user being deleted
> * Time duration of zero in "list scans" output had html mark-up
> * Tables were created without the Versioning Iterator
> * The example policy file needs to allow accumulo classes to remove files in /tmp (memory dumps can be put in /tmp for isolation purposes)
