org.apache.hadoop.security.AccessControlException: Queue root.online already has 0 applications, cannot accept submission of application

- HDP2

- YARN队列资源限制

YARN队列种新建了一个队列，分配了资源，提交spark任务到该队列的时候，出现报错：

org.apache.hadoop.security.AccessControlException: Queue root.online already has 0 applications, cannot accept submission of application

大致意思为，队列种已经有0个任务了，不能再提交任务。查看原因和分析，其他队列可以提交，通过HDP的管理界面查看队列设置，发现没有设置队列的MAX APP值，设置后刷队列，就可以了。
