Steve Loughran commented on HADOOP-16446:
-
yeah, commons-lang is a pain. The good news: it's easier to handle than guava.
We have upgraded commons lang; the JIRA for that was first filed in 2014, and
finally did it because its required for more recent versions of Java:
HADOOP-10783
if you add commons-lang as a dependency, then you get it back: commons-lang3
and commons-lang will coexist

> Hi,
> When I try to update Hadoop-common to the last version 3.2.0, it breaks
> backward compatibility due to compile dependency change in commons.lang. This
> also breaks rolling upgrades since any client implementing this - like Apache
> Crunch.
> -The following code will fail to run with the error
> "java.lang.NoClassDefFoundError:
> org/apache/commons/lang/SerializationException":
>
> {code:java}
> public void Demo(){
> PCollection data = MemPipeline.typedCollectionOf(strings(), "a");
> }
> {code}
> Thanks a lot.
