Tim Robertson updated SPARK-45855:
----------------------------------
Description:
Hi,
We've discovered code that worked in Spark 3.3.0 doesn't in 3.4.0. I can't find
anything in the release notes to indicate why, so I wonder if this is a bug.
Thank you for looking.
Here we're using our own custom codec, but we noticed we can't set gzip either.
{{ SparkConf conf = spark.sparkContext().conf();}}
{{ conf.set("hive.exec.compress.output", "true");}}
{{ conf.set("mapred.output.compression.codec", D2Codec.class.getName()); }}
{{ spark.sql("CREATE TABLE b AS SELECT id FROM a");}}
This will create the table, but it writes uncompressed files, where Spark 3.3.0
would write compressed files.
Any advice is appreciated and I can help run tests. We run Spark on K8S using
the stackable.tech distribution.
