ZKAssign.transitionNodeClosed介绍

[英]Transitions an existing unassigned node for the specified region which is currently in the CLOSING state to be in the CLOSED state.

Does not transition nodes from other states. If for some reason the node could not be transitioned, the method returns -1. If the transition is successful, the version of the node after transition is returned.

This method can fail and return false for three different reasons:

• Unassigned node for this region does not exist
• Unassigned node for this region is not in CLOSING state
• After verifying CLOSING state, update fails because of wrong version (someone else already transitioned the node)

Does not set any watches.

This method should only be used by a RegionServer when initiating a close of a region after receiving a CLOSE RPC from the Master.
[中]将当前处于关闭状态的指定区域的现有未分配节点转换为关闭状态。
不从其他状态转换节点。如果由于某种原因无法转换节点，该方法将返回-1。如果转换成功，则返回转换后的节点版本。
由于三种不同的原因，此方法可能会失败并返回false：
*此区域的未分配节点不存在
*此区域的未分配节点未处于关闭状态
*验证关闭状态后，更新因版本错误而失败（其他人已转换该节点）
不设置任何手表。
只有RegionServer在从主服务器接收到关闭RPC后启动区域关闭时，才应使用此方法。
