URL: https://github.com/apache/pulsar/issues/14624


   **Describe the bug**
   related to this issue: #14598 
   
   We have thousands of production machines. When a network problem or cluster 
failure occurs, and then the network is restored or the cluster is restored, 
and the connection is re-established, the `partitionsAutoUpdateTimerTask` will 
still not be able to get partitions information normally, this causes 
`partitionsAutoUpdateFuture` to neither fail nor complete. Then, 
`partitionsAutoUpdateTimerTask` because the previous 
`partitionsAutoUpdateFuture` did not complete. The 
topicsPartitionChangedListener.onTopicsExtended method will no longer be 
executed.

   ```
                   // if last auto update not completed yet, do nothing.
                   if (partitionsAutoUpdateFuture == null || 
partitionsAutoUpdateFuture.isDone()) {
                       partitionsAutoUpdateFuture =
                               
topicsPartitionChangedListener.onTopicsExtended(ImmutableList.of(topic));
                   }
   ```
