linux下部署的的分片集群, 开启balancer, 移动块的时候报socket连接失败, 错误信息如下:
moveChunk result: { cause: { active: false, ns: "testdb.uniques", from: "shard1/PC-2016huumjn:21001", min: { date: "2016-09", dim0: 1000000.0 }, max: { date: "2016-10", dim0: 200000.0 }, shardKeyPattern: { date: 1.0, dim0: 1.0 }, state: "fail", errmsg: "socket exception [CONNECT_ERROR] for shard1/PC-2016huumjn:21001", counts: { cloned: 0, clonedBytes: 0, catchup: 0, steady: 0 }, ok: 1.0 }, code: 96, ok: 0.0, errmsg: "data transfer error" }
