HTTP 500 Error for SparkUI in YARN Cluster mode

I got this error when I click "Track URL: ApplicationMaster" when I run a
spark job in YARN cluster mode. I found this jira
https://issues.apache.org/jira/browse/YARN-800, but I could not get this
problem fixed. I'm running CDH 5.1.0 with Both HDFS and RM HA enabled. Does
anybody has the similar issue? How do you fix this?HTTP ERROR 500
