YarnClient.updateReservation介绍

[英]The interface used by clients to update an existing Reservation. This is referred to as a re-negotiation process, in which a user that has previously submitted a Reservation.

The allocation is attempted by virtually substituting all previous allocations related to this Reservation with new ones, that satisfy the new ReservationDefinition. Upon success the previous allocation is atomically substituted by the new one, and on failure (i.e., if the system cannot find a valid allocation for the updated request), the previous allocation remains valid.
[中]客户端用于更新现有预订的接口。这被称为重新协商过程,在此过程中,之前提交过预订的用户。
通过使用满足新的ReservationDefinition的新分配几乎替换与此保留相关的所有以前的分配来尝试分配。成功后,前一次分配将被新分配原子地替换,失败时(即,如果系统无法找到更新请求的有效分配),前一次分配仍然有效。
