PhysicalOperator has a member variable (non-static) Log object that is
non-transient, this causes serialization errors

Key: PIG-1955
URL: https://issues.apache.org/jira/browse/PIG-1955
Project: Pig
Issue Type: Bug
Components: impl
Affects Versions: 0.8.0, 0.9.0
Reporter: Woody Anderson
Assignee: Woody Anderson
Fix For: 0.9.0, 0.8.0
Attachments: 1955.patch
I found this while trying to write unit tests. Creating a local PigServer to
test my LoadFunc caused a serialization of the PhysicalOperator class, which
failed due to:
..
Caused by: java.io.NotSerializableException:
org.apache.commons.logging.impl.Log4JCategoryLog
..
this is easily fixed by adding the transient keyword to the definition of log.
e.g.
on trunk:
private final transient Log log = LogFactory.getLog(getClass());
on the 0.8 tag:
private transient Log log = LogFactory.getLog(getClass());
