   Finally solved.
   
   First of all, the conclusion is that   No module named '_bz2',  
   
   ```
   yum install  bzip2-devel
   ```
   then rebuild python3.8,  and  install airflow ,   
   
   
   The process of investigation;
   1. modiry '/usr/local/python3.8/lib/python3.8/site-packages/airflow/providers/apache/hive/get_provider_info.py' append  `traceback.extract_stack()` 
   2. restart webserver , then look the  stack log
   
   3. `/usr/local/python3.8/lib/python3.8/site-packages/airflow/www/views.py` line 3341 `choices=sorted(_get_connection_types(), key=itemgetter(1)),` 
   4.  fond `provider_info(line 3334)` is none
   5.  `/usr/local/python3.8/lib/python3.8/site-packages/airflow/providers_manager.py` line 142 ` import_string(class_name)`  exception, **but the log level is debug**  , 
   i  start webserver use 'airflow webserver -d',  log  nothing.
   6.  append code `print(e)`  , restart webserver,    console  output  `No module named '_bz2',  `
   
   
   
   
   suggest:   modify `providers_manager.py(line  146)`  log level to 'error',  
   
   another question:   why  i  use   'airflow webserver -d'  start webserver ,    the debug level log not  output to  console?
