我使用hadoop 2.9.2启动了dataproc群集，下载了flink 1.7.2，并尝试使用以下命令启动它：
./bin/yarn-session.sh -n 2此操作失败，错误消息如下：
Setting HADOOP_CONF_DIR=/etc/hadoop/conf because no HADOOP_CONF_DIR was set.

通常，安装flink的最佳方法是使用初始化操作，该操作通过apt get从dataproc的发行版安装，以获取flink的版本，该版本已根据给定的dataproc版本进行交叉编译和测试。在这种情况下，不需要修改任何环境变量就可以工作。
如果您确实想将特定版本的flink与发行版中未提供该版本flink的dataproc版本一起使用，实际上您可能需要像以前一样从flink的下载中进行安装。您还可以查看初始化操作的早期版本之一，当它从tarball安装flink时，查看可能需要的配置类型。例如，基于前面的init操作，您可能还希望导出
HADOOP_CONF_DIR=/etc/hadoop/conf.lvmkulzt2#
为了解决这个问题，我需要导出以下变量：
