无法从Windows连接到HBase [英] Not able to connect to HBase from Windows

问题描述

我试图从Windows运行一个HBase Java Client程序。
我所拥有的是1）没有任何编译错误的Java程序
2）hbase-site.xml
（没有其他HDFS或HBase配置文件，只有上面的。）
当我运行该程序时，出现以下错误 - 在最后一个块中给出。我想念什么？
我在这里给予。

解决方案

I没有core-site.xml，后来我有一些连接问题
到HDFS名称节点。一旦我解决了这些问题，我就可以插入数据。

在开发将数据插入HBase的客户端程序时，我还解决了以下依赖项：
commons- lang-2.6
commons-logging-1.1.3
slf4j-1.7.5
protobuf -java-2.4.0a。

I am trying to run a HBase Java Client Program from Windows. All I have is 1) A Java Program without any compiler error 2) hbase-site.xml (No other HDFS or HBase config files I have. Only the above one.) When I run the program I get the following error-given in the last block. Do I miss something? Both I am giving here.

    {
        try
        {
            Configuration   aConfig = HBaseConfiguration.create();
            HTable          aTable  = new HTable(aConfig, "TestTable");

            byte[]          aRowKey = Bytes.toBytes("RowKey1");
            Put             aPut    = new Put(aRowKey);

            byte[]          aColFamily  = Bytes.toBytes("ColumnFamily1");
            byte[]          aColumn     = Bytes.toBytes("Column1");
            byte[]          aColumnVal  = Bytes.toBytes("ColumnValue1");

            aPut.add(aColFamily, aColumn, aColumnVal);

            aTable.put(aPut);
            aTable.close();
        }
        catch(IOException aException_in)
        {
            System.out.println("");
        }
    }
}

解决方案

I did not have core-site.xml and later I had some connectivity issues to the HDFS name node. Once I solved these I am able to insert data.

Also I resolved the following dependencies while I developed the client program that inserts data into HBase: commons-lang-2.6 commons-logging-1.1.3 slf4j-1.7.5 protobuf-java-2.4.0a .
