No, the permissions are still not correct, otherwise, Flink would not
complan.
The error message of Flink is actually pretty precise: "Caused by:
java.io.FileNotFoundException: File /user/cloudera/inputs does not exist or
the user running Flink ('yarn') has insufficient permissions to access it."
Does the file exist and does the user "yarn" has permission to access it?
