我正在尝试创建外部表并尝试将twitter数据加载到表中。创建表时出现以下错误，无法跟踪错误。

下面是hdfs路径中可用的twitter数据。如何为下面的twitter数据创建合适的表？

如果你看https://cwiki.apache.org/confluence/display/hive/languagemanual+ddl 您可以看到保留关键字的列表，其中 user 是一个。不能命名列 user .
你可以说出它的名字 user 如果需要，那么您的查询

SELECT `user` FROM table;

但正如您所看到的，这有点难看，所以最好选择一个不同的列名。

也可以使用此选项禁用检查：

SET hive.support.sql11.reserved.keywords=false;
