org.apache.accumulo.core.client.ScannerBase.addScanIterator()
Add a server-side scan iterator. @param cfg fully specified scan-time iterator, including all options for the iterator. Any changes to the iterator setting after this call are not propagated to the stored iterator. @throws IllegalArgumentException if the setting conflicts with existing iterators
