查看发现是端口被占用，查找占用6000/60020的进程并杀死：

1

[hadoop@Master logs]$ netstat -apn | grep 60000

2

4

tcp 0 0 ::ffff:192.168.1.2:60000 :::* LISTEN 17681/java

5

[hadoop@Master logs]$ kill 17681

重启仍出现这样的问题，没办法了～～～

今天再重新启动后，查看日志：

1

1、启动Hbase之前尽量关闭Hadoop的HDFS的安全模式，未关闭可能会造成Hbase在HDFS上创建文件不成功，日志记录中也会出现如下记录：

2

2012-04-10 21:37:01,999 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...

2012-04-10 21:37:12,003 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...

5

2012-04-10 21:37:32,011 INFO org.apache.hadoop.hbase.util.FSUtils: Waiting for dfs to exit safe mode...

解决方法：使用 hadoop dfsadmin -safemode leave 命令使Hadoop退出安全模式
