Sean Owen commented on SPARK-19999: ----------------------------------- Although this is going to be a very niche problem, and eventually fixed in the JDK, I imagine it's also pretty easy to patch around -- is there a drawback to special-casing this arch in the Spark code or will it have another consequence? > Test failures in Spark Core due to java.nio.Bits.unaligned() > ------------------------------------------------------------ > > Key: SPARK-19999 > URL: https://issues.apache.org/jira/browse/SPARK-19999 > Project: Spark > Issue Type: Bug > Components: Spark Core > Affects Versions: 2.1.0, 2.2.0 > Environment: Ubuntu 14.04 ppc64le > $ java -version > openjdk version "1.8.0_111" > OpenJDK Runtime Environment (build 1.8.0_111-8u111-b14-3~14.04.1-b14) > OpenJDK 64-Bit Server VM (build 25.111-b14, mixed mode) > Reporter: Sonia Garudi > Labels: ppc64le > > There are multiple test failures seen in Spark Core project with the > following error message : > {code:borderStyle=solid} > java.lang.IllegalArgumentException: requirement failed: No support for > unaligned Unsafe.
