flink 1.12.1示例应用程序在单节点纱线群集上出现故障
提问于 2021-02-25 00:45:23
我正在尝试flink示例，如中所述
flink文档
在单个节点中
纱线簇
..。
正如在本文中提到的
讨论
在执行yarn命令之前，也会像下面这样设置。
export HADOOP_CONF_DIR=/etc/hadoop/conf在执行以下命令时
ubuntu@vrni-platform:~/build-target/flink$ ./bin/flink run-application -t yarn-application ./examples/streaming/TopSpeedWindowing.jar它失败，出现以下错误

有人能告诉我出了什么问题吗？flink不支持单节点纱线集群开发吗？

我的设置中存在配置问题。在我的设置中
正在与yarn用户一起运行。
ubuntu@vrni-platform:/tmp/flink$ ps -ef | grep nodemanager
yarn 4953 1 2 05:53 ? 00:11:26 /usr/lib/jvm/java-8-openjdk/bin/java -Dproc_nodemanager -XX:+HeapDumpOnOutOfMemoryError -XX:HeapDumpPath=/var/lib/heap-dumps/yarn -XX:+ExitOnOutOfMemoryError -Dyarn.log.dir=/var/log/hadoop-yarn -Dyarn.log.file=hadoop-yarn-nodemanager-vrni-platform.log -Dyarn.home.dir=/usr/lib/hadoop-yarn -Dyarn.root.logger=INFO,console -Djava.library.path=/usr/lib/hadoop/lib/native -Xmx512m -Dhadoop.log.dir=/var/log/hadoop-yarn -Dhadoop.log.file=hadoop-yarn-nodemanager-vrni-platform.log -Dhadoop.home.dir=/usr/lib/hadoop -Dhadoop.id.str=yarn -Dhadoop.root.logger=INFO,RFA -Dhadoop.policy.file=hadoop-policy.xml -Dhadoop.security.logger=INFO,NullAppender org.apache.hadoop.yarn.server.nodemanager.NodeManager我在执行
命令as
用户和
用户没有写入权限
我的设置中的主文件夹。
ubuntu@vrni-platform:/tmp/flink$ echo ~ubuntu
/home/ubuntu
ubuntu@vrni-platform:/tmp/flink$ echo ~yarn
/var/lib/hadoop-yarnflink似乎需要拥有写入用户主目录的权限才能创建
文件夹，即使作业是在纱线中提交的。如果我用以下命令运行flink，它对我来说工作得很好
我的设置中的用户。
