   Thanks for the reply.
   We meet this issue when ESS(node manager) is busy for full gc, and the task costs long times(connectionTimeout*maxRetry*(number of requests to the same ESS)) and then became fetch failed.
   We expect the task could fast fail instead of wasting too much times to wait the lock of client.
