Could not find or load main class org.apache.hadoop.yarn.server.nodemanager.containermanager.loca lizer.ContainerLocalizer
Hi all, When we configure kerberos to submit tasks, only the primary account can be submitted successfully, and other accounts cannot be submitted. Report Could not find or load main class org.apache.hadoop.yarn.server.nodemanager.containermanager.loca lizer.ContainerLocalizer My question is the same as this https://issues.apache.org/jira/browse/MAPREDUCE-7224 issue. I saw that my cluster environment variables are fine. How can I solve this problem?
