下载解压Spark 2.1, 设置SPARK_HOME,并添加 %SPARK\_HOME%\bin 到PATH中,此时尝试在控制台运行spark-shell
,出现如下错误提示无法定位winutils.exe。

从错误消息中可以看出Spark需要用到Hadoop中的一些类库(通过HADOOP_HOME环境变量,因为我们之前并未设置过,所以文件路径null\bin\winutils.exe
里面出现了null),但这并不意味这我们一定要安装Hadoop,我们可以直接下载所需要的winutils.exe到磁盘上的任何位置,比如C:\winutils\bin\winutils.exe
,同时设置 HADOOP_HOME=C:\winutils 。
现在我们再次运行spark-shell,又有一个新的错误:

错误消息中提示零时目录 /tmp/hive 没有写的权限:
The root scratch dir: /tmp/hive on HDFS should be writable. Current permissions are: ---------
所以我们需要更新E:/tmp/hive
的权限(我在E盘下运行的spark-shell命令,如果在其他盘运行,就改成对应的盘符+/tmp/hive)。运行如下命令:
E:\>C:\winutils\bin\winutils.exe chmod 777 E:\tmp\hive
再次运行spark-shell,spark启动成功。
