我已经安装了Hive以使用Spark。根据以下文档，应在没有配置单元支持的情况下构建Spark： https://cwiki.apache.org/confluence/display/Hive/Hive+on+Spark%3A+Getting+Started
但是现在，如果我尝试使用enableHiveSupport抛出异常，那么我想在Spark代码中使用配置单元表：
Exception in thread "main" java.lang.IllegalArgumentException: Unable to instantiate SparkSession with Hive support because Hive classes are not found.

我尝试添加以下所有内容，但白费了：
export HADOOP_CONF_DIR=$HADOOP_CONF_DIR:$HIVE_HOME/conf
export HADOOP_CLASSPATH=$HADOOP_CLASSPATH:$HIVE_HOME/lib/
export HIVE_CLASSPATH=$HIVE_HOME/lib/
我想念什么吗？
