Raymond Tay created FLINK-8327:
----------------------------------
Summary: ClassLoader resolution of child-first does not appear to
work
Key: FLINK-8327
URL: https://issues.apache.org/jira/browse/FLINK-8327
Project: Flink
Issue Type: Bug
Components: Queryable State
Affects Versions: 1.4.0
Environment: h2. Description
Was trying out the {{Queryable State}} and ran into a problem where the
submitted job starts regular Akka actors and making external HTTP calls via
{{akka-http}} libraries and the flink runtime was complaining that it was not
able to read the key {{akka.http}} (this key is held in the configuration file
for {{akka-http}}).
When i ran our app on the {{sbt}} shell locally, it was able to see the key
{{akka.http}} but when we submitted the fatjar (via {{sbt-assembly}}) to flink,
it was throwing the error message (see below). Looks like a class loader issue
but i'm not sure.
Any help is much appreciated !
h3. Environment
* Local flink cluster version 1.4.0
* {{classloader.resolve-order: child-first}} in {{conf/flink-conf.yaml}}.
h3. Library version
