@Dezka Dex Problem seems to be with the ldap URL or the DN. And the error in the log shows "Root exception is java.net.SocketException: Connection reset" It could be that Active directory is set to accept connections over SSL. You may try using ldaps:// instead of ldap:// (this needs active directory cert to be imported to java cacerts)

@Karan Alang Can you check if /usr/share/java/ojdbc6.jar file exist. "/usr/hdp/current/hbase-client/lib/ojdbc6.jar" is symlink to /usr/share/java/ojdbc6.jar.

@Prajwal Kumar Can you please verify if you have hadoop proxyuser set for livy in core-site.xml. And also the error show "Server not found in Kerberos database" and the principal used is "zeppelin/host.com@DOMAIN.COM" which doesnt seems to be correct. /home/zeppelin/zeppelin.keytab keytab mentioned in interpreter must me a user principal. Something like "zeppelin-hdp25@RAGHAV.COM". Create keytab with a user principal and use that in your interpreter. And also make sure below properties are set <property>
<name>hadoop.proxyuser.livy.groups</name>
<value>*</value>
</property>
<property>
<name>hadoop.proxyuser.livy.hosts</name>
<value>*</value>
</property>

@chitrartha sur You dont need to change hadoop properties in core-site.xml. Problem is not with hadoop components, it is with hive/files view settings that needs to be modified to set webhdfs authentication to auth=KERBEROS,proxyuser=<proxyuser> Refer below doc about how to configure Ambari views if cluster is kerberized. https://docs.hortonworks.com/HDPDocuments/Ambari-2.4.0.1/bk_ambari-views/content/Kerberos_Settings.html Revert back the changes in core-site and make sure all the services are UP and follow the above doc for view setting for kerberized cluster.

@Vinay MP hive cli will start a Application Master on yarn. If you dont have enough resources on yarn, then AM launched by hive cli will stay in Accepted state until it gets the resources. As you mentioned stopping spark thrift server resolves this, it looks that you have short of resources on yarn. Spark thrift server will also lauch a AM on yarn and this AM will stay in RUNNING status until spark thrift server is stopped. If this is issue with yarn resources, you should see a reason mentioned on AM launched by hive CLI.
