Hi all, I need a help 😉 I am trying to install and launch Apache Hive meta store with PG database  on Kubernetes. The version of Hive is : apache-hive-4.0.0-bin. I configured hive-site.xml and all volume needed for Apache Hive. The init scheme was done succsufly by executing :  ./schematool -dbType postgres -initSchema Since, when try to launch hive, I obtained this error that nput name is null.   @Former Member-hive-v2-78d588-gf8rv:/opt/apache-hive-bin/bin$ hive WARNING: log4j.properties is not found.
