NPE in zookeeper trace callback
-------------------------------
Key: ACCUMULO-66
URL: https://issues.apache.org/jira/browse/ACCUMULO-66
Project: Accumulo
Issue Type: Bug
Components: trace
Reporter: Keith Turner
Assignee: Eric Newton
Priority: Minor
Saw the following when starting the shell. Seems like the callback executed
before zoo was set (or flushed from CPU cache).
