Li Lu commented on YARN-6177:
-----------------------------
Thanks [~cheersyang]. My concern is with these lines:
{code}
379 } catch (NoClassDefFoundError e) {
380 if (timelineServiceBestEffort) {
381 LOG.warn("Ignore a NoClassDefFoundError when attempting to get"
382 + " delegation token from the timeline server: " +
e.getMessage());
383 return null;
384 }
385
{code}
So if {{timelineServiceBestEffort}} is set to true, we'll leave a message and
then proceed? I was think we may not need to treat
{{timelineServiceBestEffort}} separately here since even with best effort we do
not need to keep running on errors.
