> @Daniel-009497 Thank you very much for your contribution. From my personal
point of view, this parameter should not be set to false. If it is set to
false, RM will not be able to renew token. I think this change may be
unreasonable.
@slfan1989 Noy really, if the delegation token renewer pool tracker
feature is disabled, the previous token renew logic still take effect. This new
feature is just a enhancement feature based on currently exsiting token renew
feature.
The reason why I wanna make it configurable is that we found several issues
with this new feature.
Of course, we fixed the bugs found yet, but in case of more unknown ones,
we'd better make the new feature configurable just in case. And it is a
traditional way in Hadoop community as always.
