spark-sql : Error in session initiation - NoClassDefFoundError: org/apache/tez/dag/api/SessionNotRunning

I am facing issue while initiating spark-sql session.

Initially when I initiated spark session only default database was visible (Not default database of Hive but same of Spark).

In order to view hive databases I copied hive-site.xml from hive-conf dir to spark-conf dir. After I copied hive-site.xml I am getting below error.

$ spark-sql

I am able to run pyspark and spark-shell session successfully and Hive databases are visible to me in pyspark/spark-shell session.

The error is related to tez and I confirmed that tez services are running fine. I am successfully able to access hive tables through hive2.

I am using HDP3.0 and for Hive execution engine is Tez (Map-Reduce has been removed).

@Shantanu Sharma You should not copy the hive-site.xml from hive conf directory for spark. Spark uses a smaller and rather simple hive-site.xml.

cat /etc/spark2/conf/hive-site.xml

<configuration  xmlns:xi="http://www.w3.org/2001/XInclude">
    <property>
      <name>hive.exec.scratchdir</name>
      <value>/tmp/spark</value>
    </property>
    <property>
      <name>hive.metastore.client.connect.retry.delay</name>
      <value>5</value>
    </property>
    <property>
      <name>hive.metastore.client.socket.timeout</name>
      <value>1800</value>
    </property>
    <property>
      <name>hive.metastore.uris</name>
      <value>thrift://hive-trhift-fqdn:9083</value>
    </property>
    <property>
      <name>hive.server2.enable.doAs</name>
      <value>false</value>
    </property>
    <property>
      <name>hive.server2.thrift.http.port</name>
      <value>10002</value>
    </property>
    <property>
      <name>hive.server2.thrift.port</name>
      <value>10016</value>
    </property>
    <property>
      <name>hive.server2.transport.mode</name>
      <value>binary</value>
    </property>
</configuration>

The above is an example, just make sure you change values accordingly to your env (hive.metastore.uris)

@Felix Albani

If I don't copy hive-site.xml from hive conf directory for spark then I can't see Hive databases in spark(pyspark and spark-shell).

Could you please explain me what all properties I should add in hive-site.xml of saprk and where should I update hive.metastore.uris?

If I copy below property from hive conf to spark conf, will this work?

Technical Stack Details:

HDP3.0

Spark2.3

Hive3.1

<configuration>
  <property>
  <name>hive.metastore.uris</name>
    <!-- hostname must point to the Hive metastore URI in your cluster -->
    <value>thrift://hostname:9083</value>
    <description>URI for client to contact metastore server</description>
  </property>
</configuration>

I copied /etc/hive/hive-site.xml from hive conf directory to /etc/spark2/ and then removed below properties from /etc/spark2/conf/hive-site.xml.

It's working now, I can see Hive databases in spark (pyspakr, spark-shell, spark-sql etc).

hive.tez.cartesian-product.enabled 
hive.metastore.warehouse.external.dir 
hive.server2.webui.use.ssl 
hive.heapsize 
hive.server2.webui.port 
hive.materializedview.rewriting.incremental 
hive.server2.webui.cors.allowed.headers 
hive.driver.parallel.compilation 
hive.tez.bucket.pruning 
hive.hook.proto.base-directory 
hive.load.data.owner 
hive.execution.mode 
hive.service.metrics.codahale.reporter.classes 
hive.strict.managed.tables 
hive.create.as.insert.only 
hive.optimize.dynamic.partition.hashjoin 
hive.server2.webui.enable.cors 
hive.metastore.db.type 
hive.txn.strict.locking.mode 
hive.metastore.transactional.event.listeners 
hive.tez.input.generate.consistent.splits

Do you see any consequences?

HDP 3.0 has different way of integrating Apache Hive with Apache Spark using Hive Warehouse Connector.

Below article explains the steps:
