------------------------------
Summary: 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
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.
