无法在Google Cloud Dataproc上启动Apache Flink 1.7

问题描述 投票：0回答：2

我使用Hadoop 2.9.2启动了一个Dataproc集群，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，并显示以下错误消息：

Setting HADOOP_CONF_DIR=/etc/hadoop/conf because no HADOOP_CONF_DIR was set.

要解决这个问题，我需要导出以下变量：

export HADOOP_CLASSPATH=`hadoop classpath`

通常，安装Flink的最佳方法是使用initialization action，它通过apt-get从Dataproc的发行版安装，以获得已经针对给定的Dataproc版本进行交叉编译和测试的Flink版本。在这种情况下，您不需要修改任何环境变量来使其工作。

如果您确实想要使用特定版本的Flink和Dataproc版本，而该版本在发行版中不提供该版本的Flink，实际上您可能需要像下载Flink一样安装。当你从tarball安装Flink时，你也可以查看其中一个earlier versions of the initialization action，看看可能需要的配置类型。例如，基于之前的init操作，您可能还想导出HADOOP_CONF_DIR=/etc/hadoop/conf。
