Summary: Updating incompatible issue
Key: HADOOP-16519
URL: https://issues.apache.org/jira/browse/HADOOP-16519
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 3.1.2
Reporter: xia0c
Hi,
The following code snippets throw an incompatible issue when I try to rolling
update Hadoop Common from 2.2.0 to 3.X. The Hadoop-hdfs version is 2.2.0.
{code:java}
File clusterDir = new File( "/tmp/test/" );
System.clearProperty(MiniDFSCluster.PROP_TEST_BUILD_DATA);
conf = new HdfsConfiguration();
conf.set(MiniDFSCluster.HDFS_MINIDFS_BASEDIR, clusterDir.getAbsolutePath());
MiniDFSCluster cluster = new MiniDFSCluster.Builder(conf).build();
{code}
It throws an error:
java.lang.NoSuchMethodError:
org.apache.hadoop.util.ShutdownHookManager.clearShutdownHooks()V
Thanks a lot.

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 data = MemPipeline.typedCollectionOf(strings(), "a");
}
{code}
Thanks a lot.
