正如cloudera文档中提到的，mob支持
该功能对客户端是透明的。
(https://www.cloudera.com/documentation/enterprise/5-5-x/topics/admin_hbase_mob.html)
这意味着您可以通过与任何其他列相同的方式获取存储的mob的内容。在java中：

String namespace = "nmsp";
        String tblName = "MOB_TEST";
        byte[] rowKey = "MOB_1".getBytes();
        byte[] columnFamily = "D".getBytes();
        byte[] qualifier = "MOB".getBytes();

        Get g = new Get(rowKey);
        g.addColumn(columnFamily, qualifier);

        Configuration cfg = HBaseConfiguration.create();
        Connection con = ConnectionFactory.createConnection(cfg);
        Table t = con.getTable(TableName.valueOf(namespace, tblName));

        Result r = t.get(g);
        byte[] mobContent = r.getValue(columnFamily, qualifier);

        Path outPath = FileSystems.getDefault()
                .getPath("C:/testBigFile_fromHBase.xml");
        Files.write(outPath, mobContent);
