-------------------------------------
Resolution: Won't Fix
I'm going to have to close this as a wontfix. I Feel your pain -I really do, as
I've hit it [in my own code|https://github.com/steveloughran/cloudstore]. It's
just we needed to move on, finally.

> Rolling upgrade to Hadoop 3.2.0 breaks due to backward in-compatible change
> ---------------------------------------------------------------------------
>
> Key: HADOOP-16446
> URL: https://issues.apache.org/jira/browse/HADOOP-16446
> Project: Hadoop Common
> Issue Type: Bug
> Affects Versions: 3.2.0
> Reporter: xia0c
> Priority: Major
>
> 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<String> data = MemPipeline.typedCollectionOf(strings(), "a");
> }
> {code}
> Thanks a lot.
