Robert Joseph Evans updated SPARK-40089: ---------------------------------------- Attachment: input.parquet > Doring of at least Decimal(20, 2) fails for some values near the max. > --------------------------------------------------------------------- > > Key: SPARK-40089 > URL: https://issues.apache.org/jira/browse/SPARK-40089 > Project: Spark > Issue Type: Bug > Components: SQL > Affects Versions: 3.2.0, 3.3.0, 3.4.0 > Reporter: Robert Joseph Evans > Priority: Major > Attachments: input.parquet > > > I have been doing some testing with Decimal values for the RAPIDS Accelerator > for Apache Spark. I have been trying to add in new corner cases and when I > tried to enable the maximum supported value for a sort I started to get > failures. On closer inspection it looks like the CPU is sorting things > incorrectly. Specifically anything that is "999999999999999999.50" or above > is placed as a chunk in the wrong location in the outputs. > In local mode with 12 tasks. > {code:java} > spark.read.parquet("input.parquet").orderBy(col("a")).collect.foreach(System.err.println) > {code} > > Here you will notice that the last entry printed is > {{[999999999999999999.49]}}, and {{[999999999999999999.99]}} is near the top > near {{[-999999999999999999.99]}} -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
