Java Hbase客户端连接失败

我正在尝试在远程hbase服务器和简单的web java应用程序之间建立一个简单的连接

hbase主机已启动，我可以使用端口60010上的web ui访问它

我将hbase-site.xml重新设置为默认值

这是我尝试连接的代码

public void test(){
    Configuration conf = HBaseConfiguration.create();
    conf.clear();
    conf.set("hbase.zookeeper.quorum", "<server_ip>");
    conf.set("hbase.zookeeper.property.clientPort", "2181");


    try {
        Connection connection = ConnectionFactory.createConnection(conf);

        HBaseAdmin hbaseAdmin = new HBaseAdmin(conf);

        // create a table in HBase if it doesn't exist
        String barsTableName = "Sample";
        String family = "ColumnFam";
        if (!hbaseAdmin.tableExists(barsTableName)) {
            HTableDescriptor desc = new HTableDescriptor(barsTableName);

            desc.addFamily(new HColumnDescriptor(family));
            hbaseAdmin.createTable(desc);
            Logger.info("bars table created");
        }


        Table table = connection.getTable(TableName.valueOf(barsTableName));

        Put put = new Put(Bytes.toBytes(1));
        put.add(Bytes.toBytes(family), Bytes.toBytes("descrip"), Bytes.toBytes("MaValue"));
        table.put(put);

        Get get = new Get(Bytes.toBytes(1));
        org.apache.hadoop.hbase.client.Result r = table.get(get);
        byte [] value = r.getValue(Bytes.toBytes("ColumnFam"),Bytes.toBytes("descrip"));
        String valueStr = Bytes.toString(value);
        System.out.println("GET: " + valueStr);
                connection.close();
    } catch (Exception e) {
        e.printStackTrace();
    }

}

您能否在终端中执行hbase hbck，并确保获得“发现0个不一致”

---

如果假设您没有找到“0个不一致”，则您的hbase不稳定/不一致。看起来像你的。桌子是用螺丝固定的

你检查过这个了吗？是的，但是没有帮助。你觉得有什么特别的吗？
