Ted Yu updated FLINK-5283:
--------------------------
    Description: 
{code}
   HashMap<String, RocksDBStateBackend.FinalFullyAsyncSnapshot> namedStates =
        
InstantiationUtil.deserializeObject(restoreState.iterator().next().openInputStream(),
 userCodeClassLoader);
{code}
The InputStream returned by openInputStream() should be closed upon return from 
the method.

Similar problem exists in HeapKeyedStateBackend#restoreOldSavepointKeyedState
