[jira] [Created] (YARN-10483) yarn hang住卡死，任务无法提交，切换RM主节点或重启才能恢复

--------------------------------

             Summary: yarn hang住卡死，任务无法提交，切换RM主节点或重启才能恢复
                 Key: YARN-10483
                 URL: https://issues.apache.org/jira/browse/YARN-10483
             Project: Hadoop YARN
          Issue Type: Bug
          Components: capacity scheduler, capacityscheduler, resourcemanager, RM
    Affects Versions: 3.1.1
            Reporter: jufeng li
         Attachments: RM_normal_state.stack, RM_unnormal_state.stack

yarn不定期卡死，新任务无法提交，经排查jstack日志，capacity scheduler有线程在无限等待锁，rm的cpu内存网络磁盘均正常。问题基本可以确定是capacity scheduler内部的锁除了问题。jstack日志已上传，希望有人可以解决一下，此bug比较严重，直接导致生产不可用。如果没人解答待会我再来问
