@Michael Bronson You can make the following API call to find out on how many nodes the "SPARK2_THRIFTSERVER" is installed. Please check the property "installed_count" in the response. # curl -iv -u admin:admin -H "X-Requested-By: ambari" -X GET "http://$AMBARI_SERVER:8080/api/v1/clusters/hdp/services/SPARK2/components/SPARK2_THRIFTSERVER" If you want to know the list of hosts where the "SPARK2_THRIFTSERVER" might be installed in your cluster and to know their current state you can make the following API call. # curl -iv -u admin:admin -H "X-Requested-By: ambari" -X GET "http://$AMBARI_SERVER:8080/api/v1/clusters/hdp/services/SPARK2/components/SPARK2_THRIFTSERVER?fields=host_components/HostRoles/host_name,host_components/HostRoles/state" .

The above question and the entire response thread below was originally posted in the Community Help track.

The Community Help Track is intended for questions about using the HCC site itself, not technical questions about using Ambari or upgrading HDP.

@Michael Bronson There should be ideally no Gap in time. All the cluster nodes should be in exact time sync. Else there can be many issues like Metrics data (incorrect time), Kerberos ticket issue like well known "Clock skew" error ...etc https://community.hortonworks.com/content/supportkb/187925/gssexception-failure-unspecified-at-gss-api-level.html

@dear Jay - I think we need the option uninstall lets say - in worse case we need to uninstall because some problems

jsensharma · ‎07-05-2019

@Michael Bronson You do not need to delete the whole Spark2 Service. You can delete the "SparkThrift Server" host component which are installed on the two hosts (as per your initial screenshot) and then check if your Spark2 is all working fine ... Prior to the HDP upgrade please check/run the Spark2 service check. If everything is green and running then you can start upgrading to HDP 2.6.5. Once the upgrade is completed then any time you can click on the Ambari UI --> Hosts (Tab) --> Specific Host --> "Add" (Button) and then add the "SparkThrift Server" when you need it.

@Dear Jay , thank you so much for the grate answer , just one additional question - about my post ( https://community.hortonworks.com/questions/248726/hdp-upgrade-from-264-to-265-is-it-necessary-to-upg.html ) , its not clearly if I can to upgrade HDP to 2.6.5 from 2.6.4 without ambari upgrade from 2.6.1 to. 2.6.2 so in simple words - can we just upgrade from 2.6.4 to 2.6.5 while ambari will stay with version - 2.6.1 ? its very important because on the matrix version the answer is yes but from hortonworks document the answer is different so we are very confused here - please help us to know the final answer

jsensharma · ‎07-04-2019

@Michael Bronson Yes, it is possible. But the strongly recommended approach will be to upgrade Ambari to 2.6.2.2 first and then upgrade HDP to 2.6.5.

@Michael Bronson Following doc explains step by step instruction to perform this activity (including taking various backups) https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-upgrade/content/ambari_upgrade_guide.html Getting Ready: https://docs.hortonworks.com/HDPDocuments/Ambari-2.6.2.2/bk_ambari-upgrade/content/preparing_to_upgrade_ambari_and_hdp.html Basically you will need to first upgrade Ambari and then perform the HDP upgrade.
