---------------------------------------
fuchaohong opened a new pull request, #7655:
URL: https://github.com/apache/hadoop/pull/7655
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.
