There are some known issues and blockers of 2.4.1 release.
You can check it with the following query of JIRAs:
(project = "Hadoop Common" OR project = "Hadoop HDFS" OR project =
"Hadoop YARN" OR project = "Hadoop Map/Reduce") AND "Target Version/s"
= 2.4.1 AND priority = Blocker
YARN-1929 and YARN-1934 can be critical if you're using RM-HA on some situation.
