URL: https://github.com/apache/hadoop/pull/8448#issuecomment-4311607370
> Hi @kokonguyen191 @hfutatzhanghb @ZanderXu I had the impression that
DFS_ROUTER_ASYNC_RPC_MAX_ASYNCCALL_PERMIT_KEY could control the maximum number
of requests. Is it possible to achieve the same effect using this?
I have the same question with @KeeProMise . @kokonguyen191 Could you
please clarify here?
IIUC, When we use acquirePermit, Router have put this rpc call into its call
queue. So `DFS_ROUTER_ASYNC_RPC_MAX_ASYNCCALL_PERMIT_KEY` can not control the
max calls at router side?
