Xintong Song commented on FLINK-16467:
--------------------------------------
[~michael-o] Thanks for reporting this issue.
I think this is probably due to the locale issue. We use {{String.format}} for
generating the human readable string for {{MemorySize}}, and I find this
[post|https://stackoverflow.com/questions/5236056/force-point-as-decimal-separator-in-java]
that describes the problem and how to fix it.
> MemorySizeTest#testToHumanReadableString() is not portable
