title: GCP Dataproc has Druid available in alpha. How to load segments?
body: <p>The dataproc page describing druid support has no section on how to load data into the cluster. I've been trying to do this using GC Storage, but don't know how to set up a spec for it that works. I'd expect the "firehose" section to have some google specific references to a bucket, but there are no examples how to do this. </p>
  
  <p>What is the method to load data into Druid, running on GCP dataproc straight out of the box?</p>
