Spark and Hive use separate catalogs to access SparkSQL or Hive tables in HDP 3.0 and later. The Spark catalog contains a table created by Spark. The Hive catalog contains a table created by Hive. By default, standard Spark APIs access tables in the Spark catalog. To access tables in the hive catalog, we have to edit the metastore.catalog.default property in hive-site.xml (Set that property value to 'hive' instead of 'spark'). Config File Path: $SPARK_HOME/conf/hive-site.xml Before change the config <property>
<name>metastore.catalog.default</name>
<value>spark</value>
</property> After change the config <property>
<name>metastore.catalog.default</name>
<value>hive</value>
</property>

Hi, To understand what the Yarn application is doing, check the application logs of the particular yarn application and if the job hasnot completed , Also check for the Resource manager logs if it was stuck with any errors. Thanks Arun

Hey Harsh Thanks for responding. As multiple client are requesting data to hbase, at some point, sometimes user don’t get data, EOF exception or connection interruptions occur. We are not able to track the record of requested data and size of input and output data sending to end user. Regards Vinay K

Hi I have resolved the issue. i have done all steps on that node where i was facing issue First i clean cache from /tmp to some temporary directory. Then move all keytabs from /etc/security/keytabs/ to other temporary directory and finally i restart ambari-agent where i was facing issue. Then tried regenerate keytabs which i got successfully. Now i have resumed the upgradation.

Thanks @Geoffrey Shelton Okot Also i have found the problem. Whenever we install new HDP or upgrade HDP, we specify the repository path of HDP and HDP-UTILS in UI, accordingly ambari create repo on all agents with name of HDP-2.6-repo-51, HDP-UTILS-1.1.0.22-repo-51. But i had also created HDP and HDP-UTILS repository manually on all nodes and all HDP packages had installed with manually repository path. When i was starting services, hbase client and other client find HDP-2.6-repo-51 repository for install the client which i was not getting. Now i have disable the manually repository and reinstall the client package manually. It's working fine.

What component are you asking about? What are you trying to achieve? They typically call each other over combinations of separate protocols. - HDFS and YARN interact via RPC/IPC. - Ambari Server and Agents are over HTTP & REST. Ambari also needs JDBC connections to the backing database. - Hive, Hbase, and Spark can use Thrift Server. The Hive metastore uses JDBC. - Kafka has its own TCP protocol. I would suggest starting on a specific component for the use case(s) you want. Hadoop itself is only comprised of HDFS & YARN + MapReduce
