   ### What happened + What you expected to happen
   
   There is an NPE problem in HDFSCacheLogWriter getOutputStream, and it does not judge whether the fileSystem is Null
   HDFSCacheLogWriter getOutputStream存在NPE问题，没有判断fileSystem是否为Null
   ```
   def getOutputStream: OutputStream = {
       if (null == outputStream) OUT_LOCKER.synchronized {
         if (null == outputStream) {
   
           outputStream = fileSystem.write(new FsPath(logPath), false)
         }
       }
       outputStream
     }
   ```
   You should make a short judgment when writeToFile is called, and give a Warn-level log
