我编写了一个perl脚本，其中 copyFromLocal 调用以上载文件。当它运行时 WARN ipc.Client: interrupted waiting to send params to server 发生。我检查了所有刚上传的文件。看来它们都被复制成功了。
有人知道那个警告是什么意思吗？完整的警告信息

从我自己对这个问题的研究来看，它似乎与这个bug有关：https://issues.apache.org/jira/browse/hadoop-6762
看起来已经尝试了各种修复方法，但是没有任何方法能够令人满意地解决问题。不管怎样，这只是一个警告，在我调查过的每一个警告案例中，期望的操作实际上都成功了。
