URL: https://github.com/apache/hadoop/pull/6953#issuecomment-2295009935
@ayushtkn The strange thing is that
org.apache.hadoop.yarn.util.timeline.TimelineUtils imports another class from
the same hadoop-common package as JacksonUtil.
import org.apache.hadoop.util.VersionInfo;
Is it possible that this CI task is another an older copy of hadoop-common
jar?
