at org.apache.hadoop.hdfs.DFSOutputStream$DataStreamer.run(DFSOutputStream.java:514)主要原因是重新格式化文件系统，导致master节点下的hadoop2.2.0/hdfs/name/current/VERSION中的clusterID和Slave节点下的hadoop2.2.0/hdfs/data/current/VERSION中的clusterID不一致。在浏览器输入master:50070可以发现Live Nodes为0。
解决方案是修改master节点下的clusterID使之与Slave节点下的clusterID一致，然后重启服务即可。
JAR报错问题Container launch failed for container_1573700741821_0001_01_000007 : java.lang.IllegalArgumentException: Does not contain a valid host:port authority: slave_1:33775主要原因：Hadoop nodemanager结点主机名不能带下划线_。
解决方案：修改主机名称。
sudo: unable to resolve host master解决方案如下：
? ~ sudo vi /etc/hosts
1 127.0.0.1 localhost
2 127.0.1.1 ubuntu
3 127.0.1.1 master
:wq!
通过本次实验，对集群概念有个基本的认识，在搭建过程中遇到问题不算太多，主要是对局域网组建缺乏认识深度，本集群环境可以进一步扩展，如动态增减节点，借助Zookeeper技术加以融合等在企业中是比较常见的做法。
