Hbase主服務器無法構建

Question

我正在嘗試一對Linux服務器上的雙節點hbase羣集。所有文件都被轉移過來，並且服務器上有一個正在運行的hadoop集羣，但hbase仍然拒絕完全工作。動物園管理員和地區服務器正常啓動，我甚至可以使用shell，但主人拒絕啓動。對於主日誌給出的理由是：

我的配置爲我的HBase的-site.xml中被

<configuration> 
<property> 
<name>hbase.master</name> 
<value>master:60000</value> 
</property> 

<property> 
<name>hbase.rootdir</name> 
<value>hdfs://hadoop-namenode:9000/hbase</value> 
</property> 


<property> 
<name>hbase.cluster.distributed</name> 
<value>true</value> 
</property> 



<property> 
    <name>hbase.zookeeper.property.clientPort</name> 
    <value>2222</value> 
</property> 


<property> 
<name>hbase.zookeeper.quorum</name> 
<value>master</value> 
</property> 
</configuration> 

是我的配置問題，或者是它的一些網絡問題？

Answer 1

HBase master無法解析「hadoop-namenode」的IP地址。您是否已經在主機中的/etc/hosts文件中添加了「hadoop-namenode」。您可以通過HBase主機中的ping hadoop-namenode輕鬆進行檢查。
