在idea运行spark程序报错：The root scratch dir: /tmp/hive on HDFS should be writable

win10 个人电脑，在idea运行spark程序【连接了hive】，代码类似如下：

 spark = SparkSession.builder()
        .appName(APP_NAME)
        .config("spark.master", MASTER)
        .config("spark.sql.warehouse.dir", new File(WAREHOUSE_LOC).getAbsolutePath())
        .enableHiveSupport()
        .getOrCreate();

报如下错误：

java.lang.RuntimeException: java.lang.RuntimeException: The root scratch dir: /tmp/hive on HDFS should be writable. Current permissions are: r--r--r--;
org.apache.spark.sql.AnalysisException: java.lang.RuntimeException: java.lang.RuntimeException: The root scratch dir: /tmp/hive on HDFS should be writable. Current permissions are: r--r--r--;

	at org.apache.spark.sql.hive.HiveSessionStateBuilder.org$apache$spark$sql$hive$HiveSessionStateBuilder$$externalCatalog(HiveSessionStateBuilder.scala:39)

从报错日志看，应该与文件目录权限有关系

将/tmp/hive置为777权限，命令如下：

%HADOOP_HOME%binwinutils.exe chmod 777 H:tmphive

如果没有配置HADOOP_HOME环境变量，请先配置，步骤如下：

下载hadoop winutils hadoop.dll-and-winutils.exe-for-hadoop2.7.3-on-windows_X64-master.zip解压放在D盘根目录配置环境变量： HADOOP_HOME = D:hadoop-lib
