Gabor Somogyi commented on FLINK-28112:
---------------------------------------
That message comes when "fs.allowed-fallback-filesystems" doesn't contain the
target FS. When it's set the following message comes:
{code:java}
String.format(
"Could not find a file system implementation
for scheme '%s'. The scheme is "
+ "directly supported by Flink through
the following plugin%s: %s. Please ensure that each "
+ "plugin resides within its own
subfolder within the plugins directory. See https://ci.apache";
+
".org/projects/flink/flink-docs-stable/ops/plugins.html 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/.";,
