Description

Only a subset of the configuration Property's in Accumulo are modifiable via ZooKeeper (defined by Property.isValidZooProperty).

connector.instanceOperations().setProperty(String,String) updates the provided property name with the given value in ZooKeeper. The thing that is never mentioned is that only a subset of the properties in Accumulo are allowed to be overriden in ZooKeeper. Furthermore, the user receives no indication that their call failed.

The Javadoc on setSystemProperty(String,String) should be updated to inform the users that only some properties can be changed by this method, and some information should be returned back to the user to let them know that their call did not succeed (likely an Exception).
