我尝试从部署到WildFly 8.1.0.Final上的EJB连接到HBase 0.98.5-hadoop2数据库时遇到了奇怪的问题。
此代码完全可以作为独立应用程序使用:
public static void main(String[] args) throws IOException {
Configuration config = getConfiguration();
HConnection connection = HConnectionManager.createConnection(config);
}
private static Configuration getConfiguration() {
Configuration config = HBaseConfiguration.create();
config.set("hbase.zookeeper.quorum", "hbase"); //
config.set("hbase.client.retries.number", "3"); //
config.set("hbase.cluster.distributed", "true");
return config;
}
但是当我将它包含在EJB中并从服务器运行时,我遇到了以下异常:

在Linux机器上也是如此,除了它无法找到的UnixLoginModule。
来自org.apache.hadoop.hbase.security.User的这一行发生了实际异常
private SecureHadoopUser() throws IOException {
ugi = UserGroupInformation.getCurrentUser();
}
非常简单的EJB代码说明了主题如下。无论HBase服务器是否存在,它都会失败。
package hbasetest;
import java.io.IOException;
import javax.ejb.Stateless;
import org.apache.hadoop.security.UserGroupInformation;
@Stateless
public class HbaseExecutorImpl implements HbaseExecutor {
public void test() {
try {
UserGroupInformation ugi = UserGroupInformation.getCurrentUser();
} catch (IOException ex) {
throw new RuntimeException(ex);
}
}
}
我已将HBase客户端设置为模块,此处的module.xml内容

我想知道会发生什么。看起来驻留在WildFly上的代码有错误的安全上下文,因此一些WildFly设置应该会有所帮助,但我真的不知道该怎么做。
答案 0 :(得分:0)
万一有人对此感兴趣我已经通过添加此
解决了这个问题<system export="true">
<paths>
<path name="com/sun/security/auth/module"/>
</paths>
</system>
进入module.xml的部分
由于WildFly加载类的方式,它必须添加到module.xml而不是jboss-deployment-structure.xml。
