Prabhu Joseph commented on YARN-6389: ------------------------------------- [~rohithsharma] Have tested metricslimit with hbase-1.2.6 and hadoop-3.2.0 and it is working fine. Can you check if there is any difference in the test. *Rest Api Output:* {code:java} [hbase@yarn-ats-3 centos]$ curl -s "http://yarn-ats-3:8198/ws/v2/timeline/apps/application_1553684950097_0001?user.name=hbase&fields=METRICS&&metricstoretrieve=YARN_APPLICATION_MEM_PREEMPT_METRIC&metricslimit=3" | jq .
