Spark unable to connect Hive database in HDP 3.0.1

[#1]

Hi Folks,

Hope all are doing well.!!!

I've upgrade HDP 2.6.5 to HDP 3.0.1.0-187 successfully. now i'm trying to connecting hive datbases using spark-shell, i'm unable to see any hive databases. Even i have copied /etc/hive/conf/hive-site.xml to /etc/spark2/conf/ and restarted spark service. After restart spark service, hive-site.xml to original xml file.

Have there any alternative solution to resolve the issue?

Kindly assist me to fix the issue.

@sattar As this is an older post, you would have a better chance of receiving a resolution by starting a new thread. This will also provide the opportunity to provide details specific to your environment that could aid others in providing a more accurate answer to your question.

@Vinay

Can you share your spark code let me test if you set the parameters as above?

Is your cluster kerberized?

HI @Geoffrey Shelton Okot

Following properties i have defined in custom spark2-default configuration.

spark.hadoop.hive.zookeeper.quorum

spark.hadoop.hive.llap.daemon.service.hosts

spark.datasource.hive.warehouse.load.staging.dir

spark.datasource.hive.warehouse.metastoreUri

spark.sql.hive.hiveserver2.jdbc.url

yes we're using kerberized cluster.

@Vinay

In a Kerberized cluster, you MUST add the below parameter

spark.sql.hive.hiveserver2.jdbc.url.principal = $hiveS2@REALM

The above principle you can either copy it from Advanced hive-site hive.server2.authentication.kerberos.principal or get by

$ klist -kt /etc/security/keytabs/hiveserver2.service.keytab

Please check the correct HS2 keytab in /etc/security/keytabs/ that should resolve the issue.

@Geoffrey Shelton Okot

I had already defined spark.sql.hive.hiveserver2.jdbc.url.principal=hive/_HOST@TEST.COM in configuration.

@Vinay

What do you mean by "After restart spark service, hive-site.xml to original xml file." Make sure all changes are made through Ambari otherwise it will be overwritten!
Can you give latest status ...

[#8]

@Geoffrey Shelton Okot

I had copied manually /etc/hive/conf/hive-site.xml to /etc/spark2/conf/ and restarted spark service. After restart /etc/spark2/conf/hive-site.xml changed to previous hive-site.xml which i had replaced.

Latest status is, still not able to see hive database by spark. even i have also added below properties in spark configuration:

spark.sql.hive.hiveserver2.jdbc.url.principal

spark.hadoop.hive.zookeeper.quorum

spark.hadoop.hive.llap.daemon.service.hosts

spark.datasource.hive.warehouse.load.staging.dir

spark.datasource.hive.warehouse.metastoreUri

spark.sql.hive.hiveserver2.jdbc.url

@Vinay

Can you install hive,spark clients on the hive/Spark nodes?

[#10]

@Geoffrey Shelton Okot

Hive and spark client has already installed on hive and spark node.

@Geoffrey Shelton Okot

Could you please confirm do we really need to enable Interactive query? because after enable Interactive query, i'm unable to start interactive query service. Below are the logs:
