java - Executing kafka-stream example with eclipse, fails with UnsatisfiedLinkError for librocksdbjni.dll (Can't find dependency)

Question

I am trying to run a kafka-stream wordcount example with eclipse IDE but getting following error: I have added 0.10.1.0 kafka-client and 0.10.1.0 kafka-stream as dependency in my pom file. I have also checked the dependency tree and it's using rocksdbjni-4.9 jar. Based on some read on internet, this issue has been fixed on 0.10.1.0 version of kafka but I am still getting. Any help?

Exception in thread "StreamThread-1" java.lang.UnsatisfiedLinkError: LocalTemplibrocksdbjni6935746072594020003.dll: Can't find dependent libraries

Windows is not officially supported, yet.

However, Rocksdb 4.9.0+ releases should have a Windows DLL build and should work out of the box.

For older versions, there is also as workaround as described here: http://search-hadoop.com/m/Kafka/uyzND13pNzscClkW1?subj=Re+Kafka+Streams+on+Windows+
