Description

The OperatorSubtaskState only make keyed state register with SharedStateRegistry. However, the file-merging directories's handle are wrapped in FileMergingOperatorStreamStateHandle, which is an OperatorStreamStateHandle. That means the #registerSharedStates is never called, so the registry will never delete the directories.
