Steve Loughran commented on SPARK-22903:
----------------------------------------
This may be the output writer using job attempt ID for uniqueness, and as
SPARK-33230 shows, its only unique to the second.
Looks like it's Hadoop FileOutputFormat.getUniqueFile() which assumes that a
(jobattept Id, task attempt ID) is unique for the life of the yarn cluster -or
at least long enough for the lease on the file to expire.
Now, we could have FileOutputFormat use the value of
spark.sql.sources.writeJobUUID in the job conf as a better source of
uniqueness.
