> URL: https://issues.apache.org/jira/browse/SPARK-17127
> Project: Spark
> Issue Type: Improvement
> Components: Spark Core
> Affects Versions: 2.0.0
> Environment: AArch64
> Reporter: Richael Zhuang
> Priority: Minor
> Fix For: 2.1.0
>
>
> From the spark of version 2.0.0 , when MemoryMode.OFF_HEAP is set , whether
> the architecture supports unaligned access or not is checked. If the check
> doesn't pass, exception is raised.
> We know that AArch64 also supports unaligned access , but now only i386, x86,
> amd64, and X86_64 are included.
> I think we should include aarch64 when performing the check.
