Admin.decommissionRegionServers介绍

[英]Mark region server(s) as decommissioned to prevent additional regions from getting assigned to them. Optionally unload the regions on the servers. If there are multiple servers to be decommissioned, decommissioning them at the same time can prevent wasteful region movements. Region unloading is asynchronous.
[中]将区域服务器标记为已停用，以防止将其他区域分配给它们。（可选）卸载服务器上的区域。如果有多台服务器要停用，则同时停用它们可以防止浪费的区域移动。区域卸载是异步的。
