@yassine sihi Similarly you can use the following API calls to stop the HIveServer2 & Metastore: To stop HiveServer2 on host "amb25103.example.com" # curl -u admin:admin -H "X-Requested-By: ambari" -X PUT -d '{"RequestInfo":{"context":"Stop HiveServer2","operation_level":{"level":"HOST_COMPONENT","cluster_name":"plain_ambari","host_name":"amb25103.example.com","service_name":"HIVE"}},"Body":{"HostRoles":{"state":"INSTALLED"}}}' http://amb25101.example.com:8080/api/v1/clusters/plain_ambari/hosts/amb25103.example.com/host_components/HIVE_SERVER?

@Anurag Mishra Some of the metrics list you can find here that are exposed to the AMS collector: For All kind of metrics: https://github.com/apache/ambari/tree/release-2.6.1/ambari-server/src/main/resources/common-services/AMBARI_METRICS/0.1.0/package/files/service-metrics . For particularly host specific metrics names you can refer to: https://github.com/apache/ambari/blob/release-2.6.1/ambari-server/src/main/resources/common-services/AMBARI_METRICS/0.1.0/package/files/service-metrics/HOST.txt ...

@Anurag Mishra You can use Grafana to get the Host Level metrics which are sent by Ambari Metrics Monitor to Ambari Metrics Collector, By creating a custom dashboard. (Still it will be in form of Graph and not a single file with whole data) Like: In following case i created a New Dashboard with "HOST" metrics and the metrics name is "byte_in" with Aggregator as "avg" . ...

@Anurag Mishra There is not Rest API call which can be used to capture the whole Metrics Monitors/Collectors Data in form of a file. However you can query these data from the AMS collector Hbase database using utilities like sqlline as desceribed in As mentioned on the other thread: https://community.hortonworks.com/questions/172151/data-source-for-ambari-metrics-collector.html?childToView=173755#comment-173755 ...

@Irshad Muhammed It looks like the following API call is failing with "Connection reset by peer" # curl -sS -L -w '%{http_code}' -X PUT --data-binary @/usr/hdp/current/zeppelin-server/interpreter/spark/dep/zeppelin-spark-dependencies-0.6.0.2.5.3.0-37.jar -H 'Content-Type: application/octet-stream' 'http://ip-172-31-31-102.ec2.internal:50070/webhdfs/v1/apps/zeppelin/zeppelin-spark-dependencies-0.6.0.2.5.3.0-37.jar?op=CREATE&user.name=hdfs&overwrite=True&permission=444 . This generally happens when the communication is broken (or timed out by some firewall rule) while uploading the JAR to HDFS using webhdfs API "http://ip-172-31-31-102.ec2.internal:50070/webhdfs/v1/apps/zeppelin/zeppelin-spark-dependencies-0.6.0.2.5.3.0-37.jar". Test-1) So can you please check how much time does this API call takes from your few cluster nodes? And also to see if you are able to put this JAR to HDFS using the same API call from any of your cluster node? Test-2). While you are trying to upload this JAR, Please check your NameNode log to see if there is any error/warning? . ... View more
