Evaluate to run yum update cern-hadoop-config in each Spark script

CERN Hadoop team started to change their config very frequently compared to the last years. Our Spark and Sqoop jobs fail because of non-updated config which includes connection parameters and Hadoop/Spark node urls.

We need to evaluate running yum update `cern-hadoop-config` before each Spark job running on Kubernetes pod.

Start by locating the Spark job scripts and their Kubernetes pod entry points, then inspect how configuration packages are currently installed or refreshed. The work is done when there is a validated decision about running yum update cern-hadoop-config before each job and, if approved, the relevant jobs reliably apply it without breaking execution.
