STEP 1:
Get certificate from ambari-server
echo | openssl s_client -showcerts -connect <AMBARI_HOst>:<AMBARI_HTTPs_PORT> 2>&1 | sed --quiet '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/ambari_certificate.cr
STEP 2:
Get path of ambari trustore and truststore password from Ambari properties
cat /etc/ambari-server/conf/ambari.properties |grep truststore
As per your ambari.properties below is the path and password :-
ssl.trustStore.password=refer from ambari.property file
ssl.trustStore.path=/etc/ambari-server/conf/ambari-server-truststore
STEP 3:

To resolve the issue, import the Ambari certificates to the Ambari truststore. To import the Ambari certificates, do the following:
STEP 1:
Get certificate from ambari-server
echo | openssl s_client -showcerts -connect <AMBARI_HOst>:<AMBARI_HTTPs_PORT> 2>&1 | sed --quiet '/-BEGIN CERTIFICATE-/,/-END CERTIFICATE-/p' > /tmp/ambari_certificate.cr
STEP 2:
Get path of ambari trustore and truststore password from Ambari properties
cat /etc/ambari-server/conf/ambari.properties |grep truststore
As per your ambari.properties below is the path and password :-
ssl.trustStore.password=refer from ambari.property file
ssl.trustStore.path=/etc/ambari-server/conf/ambari-server-truststore
STEP 3:
keytool -importcert -file /tmp/ambari_certificate.crt -keystore <keystore-path>

Hello @pradeep_tp, Please restart Ambari Metrics from Ambari. Sometimes due to cache/network issues also metrics get unable but restart sometimes fixes the issue. Please try and let me know how it goes! //BR Roy

You need to kinit with the username that has been granted access to the SQL server DB and tables. integrated security passes your credentials to the SQL server using kerberos "jdbc:sqlserver://sername.domain.co.za:1433;integratedSecurity=true;databaseName=SCHEMA;authenticationScheme=JavaKerberos;" This worked for me. It doesn't work, it's still facing issue with the latest MSSQL JDBC driver as the Kerberos tokens are lost when the mappers spawn (as the YARN transitions the job to its internal security subsystem) 21/05/29 19:00:40 INFO mapreduce.JobSubmitter: Submitting tokens for job: job_1616335290043_2743822

I'm trying to run a dag with airflow 1.10.12 and HDP 3.0.0 when i run the dag it gets stuck in ```Connecting to jdbc:hive2://[Server2_FQDN]:2181,[Server1_FQDN]:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2``` when i run ```beeline -u "jdbc:hive2://[Server1_FQDN]:2181,[Server2_FQDN]:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2"``` from shell, it connect to hive with no problem. I've also made a connection like this ``` Conn Id * hive_jdbc ------------- Conn Type ------------- Connection URL jdbc:hive2://centosserver.son.ir:2181,centosclient.son.ir:2181/default;serviceDiscoveryMode=zooKeeper;zooKeeperNamespace=hiveserver2 ------------- Login hive ------------- Password ****** ------------- Driver Path /usr/hdp/3.0.0.0-1634/hive/jdbc/hive-jdbc-3.1.0.3.0.0.0-1634-standalone.jar ------------- Driver Class org.apache.hive.jdbc.HiveDriver ``` and I'm not using kerberos I've also added ```hive.security.authorization.sqlstd.confwhitelist.append``` in the ambari ```Custom hive-site``` ``` radoop\.operation\.id|mapred\.job\.name||airflow\.ctx\.dag_id|airflow\.ctx\.task_id|airflow\.ctx\.execution_date|airflow\.ctx\.dag_run_id|airflow\.ctx\.dag_owner|airflow\.ctx\.dag_email|hive\.warehouse\.subdir\.inherit\.perms|hive\.exec\.max\.dynamic\.partitions|hive\.exec\.max\.dynamic\.partitions\.pernode|spark\.app\.name ``` any suggestions? I'm desperate, I've tried every way that i know but still nothing @nsabharwal @agillan @msumbul1 @deepesh1

@torafca5 Could you please try downloading the jar from the below link, http://www.congiu.net/hive-json-serde/1.3.8/hdp23/json-serde-1.3.8-jar-with-dependencies.jar Once the jar is downloaded, move the jar to the location /usr/hdp/3.0.1.0-187/hive/lib. Please place the jar on all the nodes hosting Hive services. Also, please make sure you are not using LLAP(HiveserverInteractive) to connect to the hive. add jar command does not work with LLAP. implementing the above recommendation should help overcome this issue.
