Gem problem after upgrading to latest version

[Oguzhan Yayla]

Hi all,

We just upgraded our Snowplow version to 77 Great Auk by downloading runner and storage loader from Bintray but after we ran emr etl runner we receive this traceback :

We're a bit far away from Ruby world so any help is appreciated, thanks a lot in advance!

Hi Oguzhan,

Two questions:

1. Did you upgrade from an earlier Ruby (I.e. not JRuby) version of those apps?
2. Are you using the same server as before to run these apps?

Thanks,

Alex

Hey Oguzhan,

We run into this problem from time to time. It seems like RVM is interferring with JRuby as described here. Solution is pretty straightforward:

$ unset GEM_HOME

$ unset GEM_PATH

[Oguzhan Yayla]

Hi Bernardo,

That did the trick, thanks a lot!

Cheers

[Oguzhan Yayla]

Hi Alex,

Yes to both questions. But Bernardo's solution helped. Thanks a lot.

Cheers

[Alex Dean]

Thanks both! Yes we have seen issues with the old RVM settings on a server interfering with the new JRuby apps. Great that Bernardo's solution fixed it!
