@JeffEvans I think below thread answers the same question about spark client libs on worker nodes. https://community.cloudera.com/t5/Support-Questions/Spark-on-Yarn-Do-nodes-need-Spark-installed/td-p/181241 We dont need spark clients installed on all the worker nodes, should be installed only on edge nodes.
