-----------------------------------
Summary: Flink user code classloader should have Flink classloader
as parent classloader
Key: FLINK-3236
URL: https://issues.apache.org/jira/browse/FLINK-3236
Project: Flink
Issue Type: Bug
Components: Local Runtime
Affects Versions: 0.10.1
Reporter: Stephan Ewen
Fix For: 1.0.0, 0.10.2
Right now, the user code classloader delegates to the system classloader as
parent. That works in Flink standalone settings, but not when the Flink core
classes themselves are not loaded with the system classloader (certain embedded
setups)
Giving the classloader that was used to load the Flink core classes (like for
example {{org.apache.flink.runtime.taskmanager.Task.class.getClassLoader()}}
solves that problem and does not break behavior in standalone mode.
