Hbase<踩过的坑--使用intellij idea调用JavaAPI创建预分区>

本集群 基于：

VMware Workstation12 Pro

SecureCRT 7.3

Xftp 5

CentOS-7-x86_64-Everything-1611.iso

hadoop-2.8.0.tar.gz

jdk-8u121-linux-x64.tar.gz

下面是我在使用Intellij IDEA调用JavaAPI创建预分区的时候遇到的问题，写下来，备忘

新建一个包，创建几个类，感觉应该没什么问题，运行一下，尼玛，抛异常了

原因是找不到FileSystem

但是Hadoop-common包下是用这个文件的啊，

对应的文件如下：

org.apache.hadoop.fs.LocalFileSystem
org.apache.hadoop.fs.viewfs.ViewFileSystem
org.apache.hadoop.fs.ftp.FTPFileSystem
org.apache.hadoop.fs.HarFileSystem

来发现，使用的FileSystem应该是另外一个包的：org.apahce.hadoop:hadoop-hdfs:2.8.0的，加上之后就没有没有这个异常了

         <dependency>
            <groupId>org.apache.hadoop</groupId>
            <artifactId>hadoop-hdfs</artifactId>
            <version>2.8.0</version>
        </dependency>

看一下包的文件结构：发现在引入这个包的同时引入了org.apahce.hadoop:hadoop-hdfs-client:2.8.0

# Licensed to the Apache Software Foundation (ASF) under one or more
# contributor license agreements.  See the NOTICE file distributed with

org.apache.hadoop.hdfs.DistributedFileSystem
org.apache.hadoop.hdfs.web.WebHdfsFileSystem
org.apache.hadoop.hdfs.web.SWebHdfsFileSystem
org.apache.hadoop.hdfs.web.HftpFileSystem
org.apache.hadoop.hdfs.web.HsftpFileSystem

对比一下两个包的FileSystem中的内容是不一样的

2.新异常

11785 [main] WARN org.apache.hadoop.hbase.zookeeper.RecoverableZooKeeper  - Unable to create ZooKeeper Connection
java.net.UnknownHostException: master

不识别，检查一下hbase.xml配置文件，发现写的是

<?xml version="1.0"?>
<?xml-stylesheet type="text/xsl" href="configuration.xsl"?>

</configuration>

windows当然不识别，这里有两种方法：
1).修改Windows下：C:\Windows\System32\drivers\etc\hosts文件，加上对应的IP地址和主机名

192.168.195.131 master
192.168.195.132 slave1
192.168.195.133 slave2

2).将配置文件中的master,slave1,slave2修改为响应的IP地址

这里强烈推荐在使用配置文件的时候，
a.把主机名修改为IP地址
b.把0.0.0.0修改为对应的主机IP地址

3.给出程序的完整代码与结构：
