Sean Owen commented on SPARK-2223: ---------------------------------- Is it not just because there are a lot of tests, and they generally can't be run in parallel? I agree, an hour for tests is really long, but I'm not sure if there is a problem except having lots of tests. You can run subsets of tests with Maven though to test targeted changes. > Building and running tests with maven is extremely slow > ------------------------------------------------------- > > Key: SPARK-2223 > URL: https://issues.apache.org/jira/browse/SPARK-2223 > Project: Spark > Issue Type: Bug > Components: Build > Affects Versions: 1.0.0 > Reporter: Thomas Graves > > For some reason using maven with Spark is extremely slow. Building and > running tests takes way longer then other projects I have used that use > maven. We should investigate to see why. -- This message was sent by Atlassian JIRA (v6.2#6252)
