Sqoop 从 MySQL 导入到 Hive 引发 HIVE_CONF_DIR 错误

我正在尝试使用 Sqoop 将我的 MySQL 表 Lab5 加载到 Hive。Sqoop 成功运行，并将数据从 mysql 导入到 hdfs。但抛出了以下HIVE_CONF_DIR未设置的粗体错误。我已将其HIVE_CONF_DIR设置~/.bashrc为~/.profile：

export HIVE_HOME=/usr/local/hive
export HIVE_CONF_DIR=$HIVE_HOME/conf

尽管这样做了，我仍然遇到以下HIVE_CONF_DIR错误。您能尽快帮我解决这个错误吗？

您可以尝试像这样导出 hadoop_classpath

export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:/usr/lib/hive/lib/*

然后

source ~/.bashrc
