报错背景: zookeeper安装完成之后,启动之后正常,但是查看log文件zookeeper.log时发现报错. 报错现象: -- ::, [myid:] - INFO [WorkerSender[myid=]:QuorumPeer$QuorumServer@] - Resolved hostname: 192.168.52.27 to address: /192.168.52.27 -- ::, [myid:] - INFO [WorkerReceiver[myid=]:FastLeader…

这些日子为这个错误苦恼很久了,网上找到的各种方法都试了一遍,还是没能解决. 安装好zookeeper后,运行zkServer.sh start 显示正常启动,但运行zkServer.sh status 则显示:Error contacting service. It is probably not running.查看日志,报错连接的其他三台节点都拒绝连接.后来无意中看到,有网友说需要将其他节点的zk服务都开启.当时很激动的试了下,在四台节点上都运行了zkServer.sh start,可是当运…

坑一: Cannot open channel to at election address slave1/ java.net.ConnectException: Connection refused (Connection refused) 如上情况:132 ip 3888 端口没开.通常是zookeeper服务没起 端口检查: netstat -anp | grep 3888 正常开启如下:  zookeeper 集群不像hadoop集群,在master上启动后其他的slave也启动.必须手…

1.pytorch报错:ValueError: Expected more than 1 value per channel when training, got input size torch.Size([1,512,1,1]) 2.网上查找的原因为模型中用了batchnomolization,训练中用batch训练的时候当前batch恰好只含一个sample,而由于BatchNorm操作需要多于一个数据计算平均值,因此造成该错误. 3.解决方法:在torch.utils.data.Data…
