我在windows机器上有hbase。
我试图通过java程序从另一台windows机器上访问相同的内容。
连接拒绝错误的结果。
注:
我在linux上也试过同样的方法,效果很好。我在linux机器上安装了hbase,并通过java从windows机器上访问它。只有在尝试从linux或windows访问windows hbase时才会出现问题
hbase-env.sh地址:
以下两行未注解;
set HBASE_MANAGES_ZK=true
set JAVA_HOME=C:\jdk
hbase-site.xml:
<configuration>
<property>
<name>hbase.rootdir</name>
<value>D:\hbaseInstalledPath</value>
</property>
<property>
<name>hbase.zookeeper.property.dataDir</name>
<value>D:\zookeeperDataDirPath</value>
</property>
<property>
<name>hbase.zookeeper.recoverable.waittime</name>
<value>30000</value>

<property>

<property>

<value>2181</value>
</property>
<property>
<name>hbase.zookeeper.quorum</name>
<value>'HBase running IP' , 'JavaClient IP'</value>
</property>
</configuration>
java代码:
HConnection connection=null;
Configuration config=HBaseConfiguration.create();
config.clear();
config.set("hbase.zookeeper.quorum","172.16.101.82");
config.set("hbase.zookeeper.property.clientPort","2181");
try {
connection=HConnectionManager.createConnection(config);
}
catch(Exception e)
{ }
try {
HTableInterface table=connection.getTable(TableName.valueOf("sample"));
}
catch(Exception e)
{ }
例外情况:
Exception in connection creationorg.apache.hadoop.hbase.MasterNotRunningException:
com.google.protobuf.ServiceException: org.apache.hadoop.net.ConnectTimeoutException:
20000 millis timeout while waiting for channel to be ready for connect. ch :
