回答1:

Storm recommends to use exactly 2.1.7 version of zeroMQ.

https://github.com/xumingming/storm-wiki/blob/master/Installing-native-dependencies.md

Other version are known to cause issues as there are some serious bugs. Which version of zeroMQ are you using?

Seems the OP is long gone but I'm leaving this answer in case anyone else has this problem (this page had a high page rank when I googled for the same solution)

There's an issue with some versions of ZMQ (specifically the java wrapper) that throws UnsatisfiedLinkError when you try to close a socket, like storm is doing in this case.

More info here:

https://github.com/zeromq/jzmq/issues/237

The obvious solution would be to upgrade your jzmq version (or in this case, storm version).

Cheers.
