Bugs: ACCUMULO-1556

Repository: accumulo


The Initialize class now generates clearer error messages if an initialized instance is discovered.
The messages vary depending on whether instance.dfs.uri is used.

Note that to facilitate unit testing, the verification logic in Initialize.doInit() was refactored
into a checkInit() method.

Ran initialization with patch changes on 1.4.3 cluster under CDH 4.3. Tested successful initialization
and correct emission of error messages when instance.dfs.uri was used and was not used. Also,
implemented unit tests for altered code.
