在win10的eclipse上运行一段代码需要用到hadoop。一开始报错：Could not locate executable null\bin\winutils.exe in the Hadoop binaries
按照指导下载了winutils.exe 并且配置了环境变量。再运行程序又报错：
Exception in thread "main" java.lang.RuntimeException: java.lang.RuntimeException: The root scratch dir: /tmp/hive on HDFS should be writable. Current permissions are: ---------

按照指导在win10 cmd窗口后运行 winutils.exe chmod 777 /tmp/hive
报如下错误：
ChangeFileModeByMask error (3): ???????????
哪位大神现身救助
