-----------------------------------------
Summary: ByteArrayMarshaller.create doesn't work
Key: IGNITE-26530
URL: https://issues.apache.org/jira/browse/IGNITE-26530
Project: Ignite
Issue Type: Bug
Components: compute ai3
Reporter: Vadim Pakhnushev
Assignee: Vadim Pakhnushev
{{ByteArrayMarshaller.create}} creates an instance of the marshaller that uses
the class loader of the created instance to resolve the class for creating
object to unmarshal.
The class loader of {{ByteArrayMarshaller}} is an application class loader
because the class matches the system classes pattern (its name starts with
{{org.apache.ignite}}).
So when we try to infer the class loader to load the class to unmarshal, we use
application class loader but we should use job class loader.
To reproduce this, deploy a job with a custom argument class and overridden
{{inputMarshaller}} that returns {{ByteArrayMarshaller.create()}}.
Then submit this job using the
{{argumentMarshaller(ByteArrayMarshaller.create())}} in the {{JobDecriptor}}.
The result is the following exception:
{noformat}
