flink-s3-fs-presto:1.7.0 is missing shaded com/facebook/presto/hadoop

[spoganshev]

When I try to configure checkpointing using Presto in 1.7.0 the following exception occurs:

java.lang.NoClassDefFoundError: org/apache/flink/fs/s3presto/shaded/com/facebook/presto/hadoop/HadoopFileStatus

HadoopFileStatus is indeed absent in flink-s3-fs-presto:1.7.0, while it is present in previous versions (1.6.2 for example)

I've worked it around by just adding this class to my job project:

package org.apache.flink.fs.s3presto.shaded.com.facebook.presto.hadoop;

import org.apache.flink.fs.shaded.hadoop3.org.apache.hadoop.fs.FileStatus;

public final class HadoopFileStatus {
    public static boolean isDirectory(FileStatus status) {
        return status.isDirectory();
    }

    public static boolean isFile(FileStatus status) {
        return status.isFile();
    }
}

But it's a dirty hack of course and hopefully the fix will be added in next patch release.
