When I submit a job to yarn on Yarn-perjob Mode.An error occurred during the client-side generation of the Jobgraph submitd to yarn.
Error: java.lang.NoClassDefFoundError??org/apache/orc/PhysicalWriter Because the cluster is public, there is already related flink-orc_2.12-1.14.0-csa1.6.1.0.jar package in the /opt/flink/lib directory. However ,this class is included by my jar. This class is provided by orc-core package. I have packaged it in my jar. After my attempts, the following measures can solve my problem. 1.remove the related flink-orc_2.12-1.14.0-csa1.6.1.0.jar from /opt/flink/lib directory and packaged it to my jar. 2.put the orc-core to /opt/flink/lib directory. However, I would like to know why an error occurs when placing the flink-orc_2.12-1.14.0-csa1.6.1.0.jar package in the /opt/flink/lib directory and packaging orc-core into the my jar. Env?? Flink version: flink 1.14.0 Best, Hjw
