   > Can you check the shuffle-server and executor GC? Why not using the spark 
ui? And I think if you want to analysis, it's better to show the metrics into 
dashboard.
   1 . check the shuffle-server and executor GC : 
       shuffle-server no full gc , but  jvm_memory_bytes_used is  close to 
XMX_SIZE="60g" :

    executor gc seem normal :

   2.  using the spark ui : dont`t exported the port  and need use vpn
   3.  metrics into dashboard : had show some metrics , feel shuffle server had 
too many blocked thread not normal ,but can`t find why
