. 离开安全模式方法

  bin/hadoop  dfsadmin -safemode leave


hadoop2.7.1 相对路径不能用，似乎必须用绝对路径创建？？？？


bin/hdfs dfs -mkdir input错误 提示“ls: `input': No such file or directory”
（环境是hadoop2.7 centos 64位 ）



第一步错误必须换成bin/hdfs dfs -mkdir /input




bin/hdfs  dfs -put /home/yumh/hadoop-2.7.1/etc/hadoop/*.xml /input


bin/hadoop jar share/hadoop/mapreduce/hadoop-mapreduce-examples-2.7.1.jar grep /input /output 'dfs[a-z.]+'


bin/hadoop dfs -cat /output/*

可能的问题是当前的 shell（Zsh）对通配符的展开方式导致了问题。

Hadoop 安装部署详细说明 Hadoop是什么？ （1）Hadoop 是一个有 Apache 基金会开发的分布式系统基础架构 （2）主要解决海量数据存储和海量数据分析计算问题 （3）Hadoop 通常指 Hadoop 生态圈。 Hadoop 的优势（四高） 高可靠性：Hadoop 底层维护多个数据副本，即使 Hadoop 某个计算程序或存储出现故障，也不会导致数据的丢失。 高扩展性：在集群之间分配任务数据，可方便的扩展数以千计的节点。 高效性：在 MapReduce 的思想下，Had
