Thank you for comment.

If we change the default value of
"mapreduce.jobhistory.webapp.address"(JHAdminConfig.MR_HISOTRY_WEBAPP_ADDRESS),
we should do or discuss this in another JIRA ticket. If I overlook some points,
please let me know.

You are right. And we discuss about the default value of
"mapreduce.jobhistory.webapp.address" by an another JIRA ticket.

This should be replaced with trackerHostName.startWith("tracker_") to avoid
unexpected matches.

Sure. It should not use "trackerHostName.startWith(...)" in this method.
I attach a renew patch file which reflected it.

> This is because a node name recorded in History file is not given "tracker_".
> Therefore it makes modifications to be able to read History file even if a
> node name is not given by "tracker_".
> In addition, it fixes the URL of displayed task log.
