Akira Ajisaka commented on YARN-10772:
--------------------------------------
Hi [~weichiu], thank you for your report. LongRange comes from commons-lang
2.x, so we need to add back commons-lang 2.x dependency to fix the
compatibility.
BTW, in YARN-8363, we upgraded the signature to use commons-lang 3.x, which is
still not good. If we upgrade commons-lang 4.x in the future, we break
compatibility again. Instead, I want to create a public API to avoid the use of
external library.

> Affects Versions: 3.2.0
> Reporter: Wei-Chiu Chuang
> Priority: Major
>
> YARN-8363 migrated our usage of commons-lang to commons-lang3 in 3.2.0.

> The startRange and finishRange changed type from LongRange to Range<Long>.
> It could cause problems when migrating applications, for example, from Hadoop
