morningman opened a new issue #2158: restart FE with --helper failed
URL: https://github.com/apache/incubator-doris/issues/2158
 
 
   **Describe the bug**
   If you restart a FE with `--helper` argument and the helper is not itself, FE will start failed.
   
   Because in CL #2052 , I changed the FE start logic, so that the HTTP server will no start
   until all things are ready.
   When restart a FE cluster(3 followers):
   
   1. restart the first FE, it will because UNKNOWN and waiting other FEs to start. It is not 
   ready so that its http server is not started.
   2. restart the second FE with `--helper` point to the first FE. But first FE's HTTP server is
   not started so the second FE start failed.
   
   2 of 3 FE are not start correctly, so the FE cluster start failed.
