Do you mean AccumuloInputFormat.addIterator / Scanner.addScanIterator, or
TableOperations.attachIterator?  If the former, the iterators are set as
one-time scan iterators and will not be there when you scan in the shell.
Are you setting more than one RegExFilter on the same scanner or input
format?  If so, you'll need to give them unique names using one of the
IteratorSetting constructors that takes the name as a parameter.
