我已经配置了hadoop多节点集群。当我试图在主节点中使用sqoop将一个表从mysql数据库导入hive时，它抛出了以下错误，

sqoop import --connect jdbc:mysql://master:3306/mysql --username root --password admin --table payment  --hive-import -- --null-string '\\N' \ --null-non-string '\\N'

警告：/usr/lib/hcatalog不存在！hcatalog作业将失败。

Please set $HCAT_HOME to the root of your HCatalog installation.

我试过给那个文件夹权限，但没用。

versions of technologies

请帮助我。让我知道，想要更多的信息。
提前谢谢。
