Robert Reid commented on SPARK-20894:
-------------------------------------
I'm encountering similar problems as [~aydinchavez] with 2.3. The directory it
reports that it's looking for, for delta files, doesn't match those that exist.
There's a GUID in the path that is incorrect.

> Dataset<Row> df2 = df1.groupBy(functions.window(df1.col("Timestamp5"), "24
> hours", "24 hours"), df1.col("AppName")).count();
> StreamingQuery query = df2.writeStream().foreach(new
> KafkaSink()).option("checkpointLocation","/usr/local/hadoop/checkpoint").outputMode("update").start();
> query.awaitTermination();
> This for some reason fails with the Error
> ERROR Executor: Exception in task 0.0 in stage 1.0 (TID 1)

> /usr/local/hadoop/checkpoint/state/0/0/1.delta does not exist
