Hbase报错：java.net.ConnectException: 拒绝连接

进入logs看到如下错误：

java.net.ConnectException: Call From hadoop103/192.168.248.103 to hadoop102:8020 failed on connection exception: java.net.ConnectException: 拒绝连接; For more details see: http://wiki.apache.org/hadoop/ConnectionRefused

解决：

检查hdfs中配置：core-site.xml

    	fs.defaultFS
    	hdfs://hadoop102:9820
    

与Hbase中配置：hbase-site.xml

    	hbase.rootdir
    	hdfs://hadoop102:9820/hbase
	

这两个配置的端口号9820必须一致，不然会报连不上的错误；

希望能帮到你们
