Caused by: org.apache.flink.core.fs.UnsupportedFileSystemSchemeException: Could
not find a file system implementation for scheme 'oss'. The scheme is directly
supported by Flink through the following plugin(s): flink-oss-fs-hadoop. Please
ensure that each plugin resides within its own subfolder within the plugins
directory. See
https://nightlies.apache.org/flink/flink-docs-stable/docs/deployment/filesystems/plugins/
for more information. If you want to use a Hadoop file system for that scheme,
please add the scheme to the configuration fs.allowed-fallback-filesystems. For
a full list of supported file systems, please see
https://nightlies.apache.org/flink/flink-docs-stable/ops/filesystems/.
