HBase單機模式配置以及不能建立表問題的解決方法（Caused by: java.net.ConnectException: Connection refused）

前些日子想試一試hbase，剛開始安裝了單擊版的，可是到最後建立表的時候出了錯誤，中間有一段時間作其餘的事情了，今天有空就把之前的hbase拿出來回憶回憶，

我安裝的單擊版hbase是0.92.1的，下載完直接解壓，hbase-env文件中加了

export HBASE_OPTS="-XX:+UseConcMarkSweepGC"
export JAVA_HOME=/usr/local/java/jdk1.6.0_38/

 export HBASE_MANAGES_ZK=true

hbase-site中

<configuration>

<property>
<name>hbase.rootdir</name>
<value>file:///home/bigfish/myhbase1/</value>
</property>
 <property>
	        <name>hbase.zookeeper.property.dataDir</name>
	        <value>/home/bigfish/myhbase1/zookeeper</value>
	    </property>
</configuration>

而後啓動hbase   Hmaseter啓動了   啓動  hbsae shell

list命令能夠    status命令也能夠  可是建立表的時候出錯了

查看log文件下的日誌：

說的是ip地址不能正確映射，gedit /etc/hosts查看   發現    

localhost    127.0.0.1

bigfish     127.0.1.1

二者不一值，都改成 127.0.0.1    而後重啓hbase   而後就能搞建立表了。
