类名称:YarnScheduler
方法名:removeQueue

YarnScheduler.removeQueue介绍

[英]Remove an existing queue. Implementations might limit when a queue could be removed (e.g., must have zero entitlement, and no applications running, or must be a leaf, etc..).
[中]删除现有队列。实现可能会限制可以删除队列的时间(例如,必须具有零权限,并且没有正在运行的应用程序,或者必须是叶子,等等)。

/**
 * First sets entitlement of queues to zero to prevent new app submission.
 * Then move all apps in the set of queues to the parent plan queue's default
 * reservation queue if move is enabled. Finally cleanups the queue by killing
 * any apps (if move is disabled or move failed) and removing the queue
 */
