Question

我正在尝试从Linux客户端连接到运行在不同服务器上的HBase服务器，我得到以下错误。代码在我的Windows笔记本电脑上工作正常，我能够连接到Hbase服务器并获得结果。我想我错过了一些我的linux服务器的依赖jar，因为当我添加hbase-client jar时，它可以从我的笔记本电脑上运行，这表明我的代码逻辑是正确的。正如我从笔记本电脑验证的那样，所有配置都正确选取。请提供一些建议。我在我的资源中传递了hbase-site.xml，core-site.xml，hdfs-site.xml。我的港口和动物园管理员qurom是正确的。我的kerberose代码工作正常。

代码：连接返回null :-(

this.conf = HBaseConfiguration.create();
    this.conf.set("hbase.zookeeper.quorum", zookeeperQuorum);
    this.conf.set("hbase.zookeeper.property.clientPort", port);
    this.conf.set("zookeeper.znode.parent", "/hbase-secure");
    //this.conf.set("hbase.client.retries.number", Integer.toString(35));
    //this.conf.set("zookeeper.session.timeout", Integer.toString(20000));
    //this.conf.set("zookeeper.recovery.retry", Integer.toString(1));
    this.conf.set("hadoop.security.authentication", "kerberos");
    this.conf.set("hbase.security.authentication", "kerberos");
    this.conf.set("hbase.master.kerberos.principal", userName);
    this.conf.set("user.name", userName);
try {
    this.connection = HConnectionManager.createConnection(conf);
} catch (IOException e) {
    // TODO Auto-generated catch block
    e.printStackTrace();
}

Answer 1

在例外结束时，有一行，如

＆＃34;引起：java.lang.RuntimeException：无法创建本地dir / data0 / hadoop / hbase / local / jars，＆＃34;

是否可以检查权限，用户是否有权在指定位置创建目录。

HBase连接为空，缺少依赖项，配置或某些属性
