We try to run oozie shell action on  kerberos environment (Cloudera Enterprise 5.16.2) with command spark2-submit. In script we use HiveContext(sc) to show databases  and the result shown that it shows only default database.  Result   Here is my script: job.properties nameNode=hdfs://namenode:8020 jobTracker=yarnRM queueName=jobqueuename concurrency_level=1 execution_order=FIFO  oozie.coord.application.path=${nameNode}/workflow/test/ workflowAppPath=${oozie.coord.application.path} oozie.use.system.libpath=True   workflow.xml <workflow-app name="spark-test" xmlns="uri:oozie:workflow:0.5"> <start to="spark-node"/> <kill name="Kill"/> <action name="spark-node"> <shell xmlns="uri:oozie:shell-action:0.1"> <job-tracker>${jobTracker}</job-tracker> <name-node>${nameNode}</name-node> <configuration> <property> <name>mapreduce.job.queuename</name> <value>nrtcdr.imeiimsi</value> </property> </configuration> <exec>sparksqltest.sh</exec> <argument>${wf:user()}</argument> <argument>${NOMINAL_TIME}</argument> ] <argument>principal</argument> <argument>keytab.keytab</argument> <argument>${JOB_QUEUE}</argument> <file>/scripts/sparksqltest.sh#sparksqltest.sh</file> <file>/configs/keytab.keytab#keytab.keytab</file> <file>/scripts/SparkSQLTest.jar#SparkSQLTest.jar</file>  <capture-output/> </shell> <ok to="End"/> <error to="Kill"/> </action> <end name="End"/> </workflow-app>   sparksqltest.sh #!/bin/bash WF_ID="$1" NOMINAL_TIME="$2" PRINCIPAL="${3}" KEYTAB="${4}" VALIDATE_JAR="`ls -1 SparkSQLTest.jar`"   export LIBHDFS_OPTS="-Dlog4j.configuration=./log4j.properties" kinit -k -t "${KEYTAB}" "${PRINCIPAL}" spark2-submit \ --name SparkSQL-test \ --master yarn --deploy-mode client \ --principal "${PRINCIPAL}" --keytab "${KEYTAB}" \ --queue "${JOB_QUEUE}" \ --class SparkSQLTest \ "${VALIDATE_JAR}"   SparkSQLTest.scala val sc = new SparkContext(new SparkConf().setAppName("spark-test")) var conf: SparkConf = new SparkConf() val spark = SparkSession.builder.config(conf).enableHiveSupport().getOrCreate() spark.sql("show databases").show() val sqlContext = new HiveContext(sc) sqlContext.sql("show databases").show()   There is no error just show only default databases also, please suggest what am I doing wrong?         ...
