Hive3 客戶端啓動提示The dir: /** on HDFS should be writable. Current permissions are: rwxr-xr-x

錯誤信息：

Logging initialized using configuration in file:/C:/hive/apache-hive-3.0.0-bin/conf/hive-log4j2.properties Async: true
Exception in thread "main" java.lang.RuntimeException: The dir: /tmp/hive on HDFS should be writable. Current permissions are: rwxr-xr-x

造成原因：hadoop 上的/tmp/hive 文件夾權限不夠。

解決辦法：調整/tmp/hive 的文件夾權限
