Question

如何从在Linux系统上运行的Hbase表和在窗口上运行的Java程序中获取数据无法找到可执行文件null \ bin \

//
这是我的连接代码

Configuration conf = HBaseConfiguration.create();
conf.set("hbase.zookeeper.quorum", "192.168.20.129");
conf.set("hbase.zookeeper.property.clientPort", "2181");
conf.set("hbase.master", "192.168.20.129:60010");

只需添加此方法，在连接之前调用。

private static void workaround() {
        //workaround for = java.io.IOException: Could not locate executable null\bin\winutils.exe in the Hadoop binaries.
        File workaround = new File(".");
        System.getProperties().put("hadoop.home.dir", workaround.getAbsolutePath());
        new File("./bin").mkdirs();
        try {
            new File("./bin/winutils.exe").createNewFile();
        } catch (IOException e) {
            logger.error(e);
        }
    }
