Description:
Using flink 1.11.2
I added the flink-s3-fs-hadoop jar in plugins dir but I am seeing the
checkpoints paths like
{{s3://my_app/__ENTROPY__/app_name-staging/flink/checkpoints/e10f47968ae74934bd833108d2272419/chk-3071}}
which means the entropy injection key is not being resolved. After some
debugging I found that in the
[EntropyInjector|https://github.com/apache/flink/blob/release-1.10.0/flink-core/src/main/java/org/apache/flink/core/fs/EntropyInjector.java#L97]
we check if the given fileSystem is of type {{ClassLoaderFixingFileSystem}}
and if so we check if the filesysystem is of type {{SafetyNetWrapperFileSystem
as well as it's delegate }}but don't check for
{{[ClassLoaderFixingFileSystem|https://github.com/apache/flink/blob/release-1.10.0/flink-core/src/main/java/org/apache/flink/core/fs/PluginFileSystemFactory.java#L65]}}
directly in getEntorpyFs method which would be the type if S3 file system
dependencies are added as a plugin.
