@hvanhovell yes, I have tested it.
For I'm now doing the spark unit tests in our server with the AArch64
architecture , and maybe due to the problem of openjdk(the unaligned field in
the class "java.nio.Bits" should be set TRUE when the architecture is
aarch64,it doesn't include aarch64 either) , the regular check for unaligned
access doesn't return TRUE . Thus the test suite fails with the message "No
support for unaligned Unsafe. Set spark.memory.offHeap.enabled to false".
If I include support for aarch64, the test suites pass without errors.
Though it only falls into the exception when the regular check doesn't pass
, I think include the aarch64 improves the codes' integrity.
