无法从Windows连接到HBase

Question

我试图从Windows运行一个HBase Java客户端程序。我所拥有的只有1）一个没有任何编译器错误的Java程序2)hbase-site.xml（我没有其他HDFS或HBase配置文件。只有上面的一个。）当我运行程序时，我得到了以下错误--在最后一个块中给出的。我错过了什么吗？我在这里都给出了。

            HTable          aTable  = new HTable(aConfig, "TestTable");

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

            byte[]          aColumnVal  = Bytes.toBytes("ColumnValue1");

            aPut.add(aColFamily, aColumn, aColumnVal);

            aTable.put(aPut);
            aTable.close();

Answer 1

我没有core-site.xml，后来我遇到了一些到HDFS name节点的连接问题。一旦我解决了这些问题，我就可以插入数据了。

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