When Observer NN replays the OP_DELETE operation which deletes a large directory, involving tens of millions of metadata. Because the operation is synchronous, the Observer NN is stuck for nearly 50 minutes. [HDFS-16043](https://issues.apache.org/jira/browse/HDFS-16043) has solved the asynchronous deletion on the active NN.
