Description

Accumulo may dump memory while a scan is running and transparently switch iterators from memory to file. If an iterator calls deepcopy after this happens, then seek will fail on the deep copy.

java.lang.NullPointerException
	at org.apache.accumulo.server.tabletserver.InMemoryMap$MemoryDataSource.iterator(InMemoryMap.java:349)
	at org.apache.accumulo.core.iterators.system.SourceSwitchingIterator.seek(SourceSwitchingIterator.java:163)
