【求助】Flink Hadoop依赖问题
我在使用Flink 1.11.0版本中，使用docker-compose搭建，docker-compose文件如下：
version: "2.1"
services:
jobmanager:
image: flink:1.11.0-scala_2.12
expose:
- "6123"
ports:
- "8081:8081"
command: jobmanager
environment:
- JOB_MANAGER_RPC_ADDRESS=jobmanager
- HADOOP_CLASSPATH=/data/hadoop-2.9.2/etc/hadoop:/data/hadoop-2.9.2/share/hadoop/common/lib/*:/data/hadoop-2.9.2/share/hadoop/common/*:/data/hadoop-2.9.2/share/hadoop/hdfs:/data/hadoop-2.9.2/share/hadoop/hdfs/lib/*:/data/hadoop-2.9.2/share/hadoop/hdfs/*:/data/hadoop-2.9.2/share/hadoop/yarn:/data/hadoop-2.9.2/share/hadoop/yarn/lib/*:/data/hadoop-2.9.2/share/hadoop/yarn/*:/data/hadoop-2.9.2/share/hadoop/mapreduce/lib/*:/data/hadoop-2.9.2/share/hadoop/mapreduce/*:/contrib/capacity-scheduler/*.jar
volumes:
- ./jobmanager/conf:/opt/flink/conf
- ./data:/data
taskmanager:
image: flink:1.11.0-scala_2.12
expose:
- "6121"
- "6122"
depends_on:
- jobmanager
command: taskmanager
links:
- "jobmanager:jobmanager"
environment:
- JOB_MANAGER_RPC_ADDRESS=jobmanager
volumes:
- ./taskmanager/conf:/opt/flink/conf
networks:
default:
external:
name: flink-network
hadoop-2.9.2已经放在data目录了，且已经在jobmanager和taskmanager的环境变量里添加了HADOOP_CLASSPATH，但通过cli提交和webui提交，jobmanager还是提示报Could not find a file system implementation for scheme 'hdfs'。有谁知道是怎么回事吗？

你可以在Pod里面确认一下/data目录是否正常挂载，另外需要在Pod里ps看一下
起的JVM进程里的classpath是什么，有没有包括hadoop的jar
当然，使用Roc Marshal建议的增加flink-shaded-hadoop并且放到$FLINK_HOME/lib下也可以解决问题
Best,

你好，Z-Z,
可以尝试在 https://repo1.maven.org/maven2/org/apache/flink/flink-shaded-hadoop-2-uber/ 下载对应的uber jar包，并就将下载后的jar文件放到flink镜像的 ${FLINK_HOME}/lib 路径下，之后启动编排的容器。
祝好。
