Hi! Thanks for diagnosing this - the fix you suggested is correct.
Can you still share some of the logs indicating where it fails? The reason is that the fallback code path (using "hdfs://localhost:12345") should not really try to connect to a local HDFS, but simply use this as a placeholder URI to get the correct configuration for Hadoop's file system.
