That's not fun.

How did you acquire Logstash? Are you running it from source, or did you download a precompiled package?

Thanks for the reply Yaauie. Not sure what happened but I downloaded the logstash.zip again and it worked.

I'm having the same issue here and downloading the package again didn't solve it.

It's running on a mac, java version 1.8.0\_171.

What can I try? There is any way I can see a more verbose error to debug this?

Thanks a lot

@yaauie regarding to your question on Divit's original post, in my case I downloaded it from the elastic site in .tar.gz format. Same one installed on another computer and it worked (also a mac), Same java version.
