Hi @kortemik,
Can you give us a hint where the Zeppelin integrates Hadoop-lzo?

[kortemik]

Hi,

I think Scalding interpreter pulls it as a dependency:
[INFO] Including com.hadoop.gplcompression:hadoop-lzo:jar:0.4.19 in the shaded jar.

You are right.
By the way, Scalding itself is licensed under the Apache License 2.0. https://github.com/twitter/scalding/blob/develop/LICENSE
The library was added with the commit in scaling. twitter/scalding@92a633d

I am far from being a licensing expert, but maybe you can address a similar problem in the Scaling project.

There we have it twitter/scalding#1932 (:
