Dongjoon Hyun resolved SPARK-28433. ----------------------------------- Resolution: Fixed Assignee: huangtianhua Fix Version/s: 3.0.0 This is resolved via https://github.com/apache/spark/pull/25186 > Incorrect assertion in scala test for aarch64 platform > ------------------------------------------------------ > > Key: SPARK-28433 > URL: https://issues.apache.org/jira/browse/SPARK-28433 > Project: Spark > Issue Type: Improvement > Components: SQL > Affects Versions: 3.0.0, 2.4.3 > Reporter: huangtianhua > Assignee: huangtianhua > Priority: Minor > Fix For: 3.0.0 > > > We ran unit tests of spark on aarch64 server, here are two sql scala tests > failed: > - SPARK-26021: NaN and -0.0 in grouping expressions *** FAILED *** > 2143289344 equaled 2143289344 (DataFrameAggregateSuite.scala:732) > - NaN and -0.0 in window partition keys *** FAILED *** > 2143289344 equaled 2143289344 (DataFrameWindowFunctionsSuite.scala:704) > we found the values of floatToRawIntBits(0.0f / 0.0f) and > floatToRawIntBits(Float.NaN) on aarch64 are same(2143289344), first we > thought it's something about jdk or scala, but after discuss with jdk-dev and > scala community see > https://users.scala-lang.org/t/the-value-of-floattorawintbits-0-0f-0-0f-is-different-on-x86-64-and-aarch64-platforms/4845 > , we believe the value depends on the architecture. -- This message was sent by Atlassian JIRA (v7.6.14#76016) --------------------------------------------------------------------- To unsubscribe, e-mail: issues-unsubscr...@spark.apache.org For additional commands, e-mail: issues-h...@spark.apache.org
