When running StormCrawler using the ElasticSearch archetype version 2.1.0, in combination with Apache Storm version 2.2.0 and OpenJDK 11, I get the following error when running the default topology:
10:51:54.160 [main-SendThread(localhost:2000)] WARN o.a.s.s.o.a.z.ClientCnxn - Session 0x0 for server localhost/<unresolved>:2000, unexpected error, closing socket connection and attempting reconnect
java.lang.IllegalArgumentException: Unable to canonicalize address localhost/<unresolved>:2000 because it's not resolvable

What does this mean and how can it be corrected?
Just found this sorry for the late reply but just in case someone else has this problem
According to Apache Storm local cluster "Unable to canonicalize address", this can be fixed by using Storm 2.1.0
