Martijn Visser commented on FLINK-31366:
----------------------------------------
[~masteryhx] What do you mean with packaged? You've downloaded them both and
put each of them in their own folder in the plugins directory, per
https://nightlies.apache.org/flink/flink-docs-master/docs/deployment/filesystems/plugins/
?
> Exception is thrown when s3a and s3p are used together

> h3. Exception
> When s3a and s3p plugins exist at the same time, an exception will be thrown
> as below:
> {code:java}
> Caused by:java.lang.NoSuchMethodError:
> org.apache.flink.fs.s3.common.AbstractS3FileSystemFactory.<init>
> (Ljava/lang/String;Lorg/apache/flink/fs/s3presto/common/HadoopConfigLoader;)
> {code}
> h3. Why
> In the construction method of AbstractS3FileSystemFactory, s3a shades
> HadoopConfigLoader into
> org.apache.flink.fs.s3hadoop.common.HadoopConfigLoader, and s3p shades
> HadoopConfigLoader into org.
> apache.flink.fs.s3presto.common.HadoopConfigLoader when package.
> (see shade-plugin)
>
> But the AbstractS3FileSystemFactory class will only be loaded once when
> loading even if there are two plugins.
> So it may first uses s3a plugin to load AbstractS3FileSystemFactory, and the
> construction method is loaded into AbstractS3FileSystemFactory(String name,
> org.apache. flink.fs.s3hadoop.common.HadoopConfigLoader hadoopConfigLoader),
> at this time s3p will be abnormal when it is constructed.
