Hi,
I am converting a storm topology to Flink-storm topology using the flink-storm
dependency. When I run my code the FlinkTopologyBuilder eventually calls
createTopology method in TopologyBuilder and throws the error at the following
highlighted line:-
public StormTopology createTopology() {
Map<String, Bolt> boltSpecs = new HashMap<String, Bolt>();
Map<String, SpoutSpec> spoutSpecs = new HashMap<String, SpoutSpec>();
for(String boltId: _bolts.keySet()) {
IRichBolt bolt = _bolts.get(boltId);
ComponentCommon common = getComponentCommon(boltId, bolt);
boltSpecs.put(boltId, new
Bolt(ComponentObject.serialized_java(Utils.serialize(bolt)), common));
}

You're probably bundling the Storm jars with your topology jar.

Looks like some bad storm dependencies are getting in the project. May I
request to please assist what might be going wrong?
I also emailed the dev community, and got the following response. Following
that did not help either
Hi,
I am not sure if this is useful, I once had similar issue.
Are you including storm-core dependency in your project? flink-storm
dependency doesn't need any specific storm-core dependency.
Just including flink-storm and removing storm-core dependency worked for me.
This has more information,
