A large number of Travis runs are failing due to what looks like errors setting up a Hadoop environment. For example: https://travis-ci.org/apache/incubator-airflow/jobs/131617413 (scroll to bottom). It looks like the first error is:
mkdir -p /user/hive/warehouse mkdir: cannot create directory `/user': Permission denied Bizarrely, it doesn't happen every time. Here's a run from the same PR which completed setup (and failed for a different reason): https://travis-ci.org/apache/incubator-airflow/jobs/131617415 Is anyone familiar with this Hadoop setup? I assume it's related to testing HiveOperators?
