   `HelixTaskExecutor-message_handle_thread_10` thread was preloading the 
segment, and this is already unexpected. 
   
   segment preloading should be done by a separate preloading thread pool whose 
thread name should be like 'segment-preload-thread-xx'
   
   so somehow server entered the preloading logic unexpected, and did it on 
helix thread unexpectedly too.
   
   this reminded me of a fix I did weeks ago (but after 1.2.0): 
https://github.com/apache/pinot/pull/13747 to refine the check of enabling 
segment preloading.
