Li Lu commented on YARN-3276:
-----------------------------
The -1 appears to be irrelevant to the fix in this patch. I can confirm we
actually have one findbugs warning in TimelineMetric, reverse comparator. Will
open a separate JIRA to do a quick fix.
> Refactor and fix null casting in some map cast for TimelineEntity (old and
> new) and fix findbug warnings
