########## common/kvstore/src/main/java/org/apache/spark/util/kvstore/LevelDBIterator.java: ########## @@ -182,23 +193,34 @@ public boolean skip(long n) { @Override public synchronized void close() throws IOException { - db.notifyIteratorClosed(this); + db.notifyIteratorClosed(it); if (!closed) { - it.close(); - closed = true; - next = null; + try { + it.close(); + } finally { + closed = true; + next = null; + cancelResourceClean(); Review Comment: Yes, we have discussed this issue. The reason for not directly calling `this.cleaner.clean()` is because the close process in `Cleaner` has added the operation of `synchronized (this._db)`, which is slightly different from the semantics of the original `close()` method.
