Hbase常见配置问题解决

问题描述：执行命令start-hbase.sh启动hbase，jps没有查看到HMaster进程，通过查看log文件发现如下错误：

2013-10-31 23:47:50,652 ERROR org.apache.hadoop.hbase.master.HMasterCommandLine: Failed to start master

问题解决：

本人hbase-site.xml配置如下：



1、进入hbase安装目录下lib目录，删除对应hadoop-core-1.0.4.jar的jar包（本人安装hadoop版本为1.2.1），删除完成后拷贝hadoop安装目录下

hadoop-core-1.2.1.jar的jar文件到该目录。

2、修改/etc/hosts文件，更改hostname对应的IP地址为当前正确的IP128.128.86.111
3、重新启动hbase
