ACCUMULO-802 Apply Sean Hickey's patch (v5)
ACCUMULO-802 Fixed NullPointerException during CloneTable due to loadbalancer trying to get the configuration before the namespace is put under the table in zookeeper. Fixed another NullPointerException with the -tn shell option for online, offline, and du. Added -tn option to shell config command. First attempt at adding a randomwalk test for namespaces, fails currently.
ACCUMULO-802 Updated ShellServer test with code that didnt fit in the patch correctly
ACCUMULO-802 Fixed a problem with RandomWalk's CloneTable, forgot to have it create a namespace. Randomwalk doesn't fail as fast, but still doesn't run correctly
ACCUMULO-802 Many small fixes. Largest change was adding CloneNamespace which clones all the tables in a namespace to a new namespace.
ACCUMULO-802 Lookup namespace config dynamically per table
