在Win7系统，eclipse读取Hbase运行报错：

问题1：

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

如果HADOOP_HOME为空，必然fullExeName为null\bin\winutils.exe。进入你的hadoop-x.x.x/bin目录下看，你会发现你压根就没有winutils.exe这个东东。去github下载一个。地址：https://github.com/srccodes/hadoop-common-2.2.0-bin

1st way :

1.Download the file

2.Create hadoop folder in Your System ex " C:"

3.Create bin folder in hadoop directory ex : C:\hadoop\bin

4.paste winutils.exe in bin ex: C:\hadoop\bin\winuitls.exe

5.In User Variables in System Properties -> Advance System Settings

Create New Variable Name: HADOOP_HOME Path: C:\hadoop\

2nd Way :

You can set hadoop home directly in Your Java Program with the following Command like this :

System.setProperty("hadoop.home.dir","C:\hadoop" );

问题2：

org.apache.hadoop.hbase.MasterNotRunningException: The node /hbase is not in ZooKeeper. It should have been written by the master. Check the value configured in ‘zookeeper.znode.parent‘. There could be a mismatch with the one configured in the master

设置如下即可：

conf.set("zookeeper.znode.parent","/hbase-unsecure");
