----------------------------------
Summary: 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
Fix For: 1.9.0
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

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) ?
