Hi Mingliang,
Oh I see. You will also have to add the Jars to the TaskManager then.
You have these options:
1. Include them directly in the TaskManager classpath
2. Include them as dependencies to the JobServer, which will cause them
to be attached to Flink's JobGraph.
Do I understand correctly that you already did (2)?
Cheers,
Max

Yes Max, I did add these Hadoop jars. The error
message from task manager was about missing HDFS file system class from
beam-sdks-java-io-hadoop-file-system module, which I also shadowed into
job server.
I see the artifact directory is successfully created at HDFS by job
server, but fails at task manager when reading.
Best,
Mingliang

Recent versions of Flink do not bundle Hadoop anymore, but they are
still "Hadoop compatible". You just need to include the Hadoop jars in
the classpath.
Beams's Hadoop does not bundle Hadoop either, it just provides Beam file
system abstractions which are similar to Flink "Hadoop compatibility".
You probably want to add this to the job server:
shadow library.java.hadoop_client
shadow library.java.hadoop_common
Cheers,
Max
