我有一个关于 map/reduce 执行的问题。
我有一个字数代码我执行它。(我有 2 个奴隶和 1 个主人)。我怎么知道slave 2被执行了？我该怎么做 println在控制台中获取从属执行时的通知？
好吧，我在函数映射的部分尝试了这个 astuce:
String ip = InetAddress.getLocalHost().getHostAddress().toString();
我使用 IP 并将其作为 key 发送(值为
new intWritable所以reduce接收执行map代码的slave的IP并将其写入输出文件。但这并不成功，因为它写了从站 1 或从站 2 的 IP 地址，而不是 2 个从站的地址，我使用的是:DistributedCache.addCacheFile(link,job.getConfiguration());
用于在所有从属服务器上分发所有文件(不是文件的一部分到每个从属服务器)。
最后我得到:
