Arvid Heise commented on FLINK-15355:
-------------------------------------
[~liyu], you are right this issue is related to the unshading. Analysis of the
issue:
* In the system classloader, there is flink-dist and hadoop-uber.
* The plugin classloader contains our s3 filesystem and the s3 hadoop
implementation.
* During initialization, the s3 hadoop implementation uses the `ServiceLoader`
to load all hadoop FileSystems.
* Classloader finds not only the expected service definitions but also those
of hadoop-uber.
* `ServiceLoader` tries to load all file systems but ofc cannot load those of
hadoop-uber because of inconsistent class hierarchies (mixed plugin and system
classloader)
* `ServiceLoader` issues warning that trigger the `check_error` script to fail.
Firstly, I verified if this is a fundamental issue in the interplay of plugins
and libraries or a cosmetic. I successfully mixed plugins and libraries by
reading from a local HDFS and writing to S3 minio and vice versa.
I implemented a solution [https://github.com/apache/flink/pull/10845] that
limits the scope of services to plugins from the plugin perspective. That gives
the desired isolation but may require users to add more jars to the plugin
folder in the worst case (security provider?). On the other hand, that use case
would allow users to use different versions of security providers for different
plugins.
We also need to investigate if the sketchy reinitialization of `FileSystem`s in
`BucketingSink` is working with plugins.
