錯誤如下:
Caused by: java.lang.IllegalArgumentException: java.net.UnknownHostException: master at org.apache.hadoop.security.SecurityUtil.buildTokenService(SecurityUtil.java:373) at org.apache.hadoop.hdfs.NameNodeProxies.createNonHAProxy(NameNodeProxies.java:258) at org.apache.hadoop.hdfs.NameNodeProxies.createProxy(NameNodeProxies.java:153) at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:602) at org.apache.hadoop.hdfs.DFSClient.<init>(DFSClient.java:547) at org.apache.hadoop.hdfs.DistributedFileSystem.initialize(DistributedFileSystem.java:139)
造成報錯的原因:
hbase-site.xml
hdfs://master:9000/hbase 的master需要在hosts檔案下配置
<configuration> <property> <name>hbase.rootdir</name> <value>hdfs://master:9000/hbase</value> </property> <property> <name>hbase.cluster.distributed</name> <value>true</value> </property> <property> <name>hbase.master.port</name> <value>16000</value> </property> <property> <name>hbase.zookeeper.property.dataDir</name> <value>/usr/local/data/zkdata</value> </property> <property> <name>hbase.zookeeper.quorum</name> <value>node1,node2,node3</value> </property> <property> <name>hbase.zookeeper.property.clientPort</name> <value>2181</value> </property> </configuration>
解決方案:
修改Linux下的/etc/hosts檔案,更改成如下
192.168.25.121 node1 master
192.168.25.122 node2
192.168.25.123 node3
