Fix Version/s: (was: 1.9.0)
Closing this in favor FLINK-13448
> Test fail on ARM
> ----------------
>
> Key: FLINK-13412
> URL: https://issues.apache.org/jira/browse/FLINK-13412
> Project: Flink
> Issue Type: Bug
> Components: Tests
> Affects Versions: 1.9.0
> Reporter: wangxiyuan
> Priority: Trivial
>
> We hit some test failures when running `mvn verify` for Flink on ARM arch.
> --------------------------------------------------------------------------------------------------------------------------
> 1. org.apache.flink.util.MemoryArchitectureTest
> [ERROR]
> testArchitectureNotUnknown(org.apache.flink.util.MemoryArchitectureTest) Time
> elapsed: 0.024 s <<< FAILURE!
> java.lang.AssertionError: Values should be different. Actual: UNKNOWN
> at
> org.apache.flink.util.MemoryArchitectureTest.testArchitectureNotUnknown(MemoryArchitectureTest.java:34)
>
> 2. org.apache.flink.table.expressions.SqlExpressionTest
> testArithmeticFunctions org.junit.ComparisonFailure: Wrong result for:
> [LOG(3,27)] optimized to: [3.0000000000000004440E0] expected:<3.0[]> but
> was:<3.0[000000000000004]>
> --------------------------------------------------------------------------------------------------------------------------
> For the first one, I think we should add `aarch64` to the knonwn arch list as
> well.
>
> For the second one, the logarithms behavior is a little different between arm
> and x86 .For example log(3,27) or log(7,343), the result is 3.0 on x86 but
> 3.0000000000000004 on arm, can we remove the test log(3,27), or change to
> something like log(2,8) ?
