ASF GitHub Bot commented on FLINK-6606: --------------------------------------- Github user rmetzger commented on the issue: https://github.com/apache/flink/pull/3933 Till and I had an offline discussion about this. What you can do in your user code to set the TCCL properly is the following: ``` Thread.currentThread().setContextClassLoader(this.getClass().getClassLoader()); ``` `this` points in user code to a class loaded through the user code classlaoder. So `this.getClass().getClassLoader()` is the CL you need to set for the thread. > Create checkpoint hook with user classloader > -------------------------------------------- > > Key: FLINK-6606 > URL: https://issues.apache.org/jira/browse/FLINK-6606 > Project: Flink > Issue Type: Bug > Components: State Backends, Checkpointing > Reporter: Eron Wright > Assignee: Eron Wright > Priority: Blocker > Fix For: 1.3.0 > > > Flink should set the thread's classloader when calling the checkpoint hook > factory's `create` method. Without that, the hook is likely to fail during > initialization (e.g. using ServiceLoader). -- This message was sent by Atlassian JIRA (v6.3.15#6346)
