Answer 1

Try this:

import org.apache.hadoop.conf.Configuration
import org.apache.hadoop.fs.{FileSystem, Path}

val fileSystem = FileSystem.get(new Configuration())
val path = new Path("/tmp/foo/bar/meow.parquet")
if (fileSystem.exists(path)){
    // TODO ...
}

It will work on local, Docker and remote file-systems (S3 & HDFS) fluently

Hope it helps
