java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.

找不到hadoop的二进制文件winutils.exe。

1.读取hbase数据你首先需要一个client,jar包里不集成windows环境client的。

2.你需要一个可以运行的client——windows环境下就是exe(hbase默认是安装在linux下的)。

3.hbase是完全依赖hadoop的,hadoop为了满足windows用户,提供了启动环境,在hadoopX.X/bin/下边的winutils.exe。(可以到github下载https://github.com/srccodes/hadoop-common-2.2.0-bin,同样也可以适用于hadoop2.6.X)

4.此路径的引用是用HADOOP_HOME变量或者是hadoop.home.dir配置都可以读取的,我们可以在代码中指定位置。System.setProperty("hadoop.home.dir", "D:/hadoop-common-2.2.0");java设置系统环境变量,其中winutils.exe就在D:/hadoop-common-2.2.0/bin/就目录下(建议这样方便)

5.也可以通过配置系统环境变量HADOOP_HOME和PATH,重启eclipse即可。
