@Santhosh B Gowda thank you! the name works. but the command i didn't work through. does the url equals https:// or service host>:<ambari port or component port>??? if it is ambari:ambari i got "curl: (35) gnutls_handshake() failed: An unexpected TLS packet was received."

i am setting component recovery by curl -u admin:admin -H "X-Requested-By: ambari" -X PUT 'http://10.90.3.101:8080/api/v1/clusters/hdp_cluster/components?ServiceComponentInfo/component_name.in(APP_TIMELINE_SERVER,DATANODE,HBASE_MASTER,HBASE_REGIONSERVER,HISTORYSERVER,HIVE_METASTORE,HIVE_SERVER,MYSQL_SERVER,NAMENODE,NODEMANAGER,RESOURCEMANAGER,SECONDARY_NAMENODE,WEBHCAT_SERVER,ZOOKEEPER_SERVER)' -d '{"ServiceComponentInfo" : {"recovery_enabled":"true"}}' but it seems the spark history serve doesn't match SPARK_HISTORY_SERVER or SPARK_HISTORY or SPARK_SERVER what is its name? or how can i get all the COMPONENTS'NAME?

map.memory = 2G map.opt=2048M io.sort.mb=2047M will cause ERROR JAVA HEAP SIZE map.memory = 2G map.opt=3096M io.sort.mb=2047M is fine; why?

i create a new client host outside the cluster by copying directory hdp & current & /etc/<conf> of one of the cluster's host i can run hive but when i run hive through different users at the same time,there is only one can be running ,others will wait until the running one finish. how to change it?

@Jay SenSharmathanks.but i mean why i need to do this on all hosts while using default choice don't.And i still can't find jdk on hosts by using "find / -name '*jdk* -type d'"

i find out that if i setup ambari with "ambari-server setup -j /path/to/your/installed/jdk". when i come to the confirm hosts step, i get warning : there are JDK issues on the hosts but when i change to configurate jdk with downloading from hortonworks,there is no issues,but i still can't find jdk on the hosts.why? please tell me how it works.
