fuchaohong updated HDFS-17776:
------------------------------
Description: In our production environment, we noticed a consistent
10-second delay when the NameNode retrieves edit logs during startup. After
investigation, the issue was traced to the /etc/resolv.conf file containing
unreachable nameserver configurations. This caused DNS resolution timeouts
during the process.
> The validRequestors in GetJournalEditServlet do not need to be regenerated
> every time.
