[jira] [Commented] (ARROW-3260) [CI] Make linting a separate job

["Krisztian Szucs (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/ARROW-3260?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=16618886#comment-16618886 ] 

Krisztian Szucs commented on ARROW-3260:
----------------------------------------

I've create a PR for reproducing CI build via docker compose: https://github.com/apache/arrow/pull/2572

So something like the following is possible:
{code:bash}
docker-compose run python flake8
{code}

We could define the linux CI builds in dockerfiles and just simply run them on travis. We could even benefit from docker's caching mechanism.

> When pushing changes I get routinely frustrated because Travis-CI fails early on a linting failure. It would be nice if linting (Python, C++) was a separate job so as not to disrupt the development workflow so much.
