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).
The issue occurred because I copied hive-site.xml from /etc/hive/conf to /etc/spark/conf in order to view databases in spark and Hive3.1 hive-site.xml has exhaustive list of newly added properties those are not compatible with spark-sql.
HDP3.0
Spark2.3
Hive3.1
So after copying hive-site.xml to /etc/spark/conf, I removed below properties from spark /etc/spark/conf/hive-site.xml
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
