Spark application syncing with Hive metastore - "There is no primary group for UGI spark"-CodePudding

I'm running a simple Spark job on Kubernetes cluster that writes data to HDFS with Hive catologization. For whatever reason my app fails to run Spark SQL commands with the following exception:

21/09/22 09:23:54 ERROR SplunkStreamListener: |exception=org.apache.spark.sql.AnalysisException

I'm connecting to Hive metastore via Thrift URL. The docker container runs the application as non-root user. Are there some kind of groups I need the user to be added to sync with the metastore?

CodePudding user response：

Try add this before setting up the spark context

System.setProperty("HADOOP_USER_NAME", "root")
