Migration from Hadoop to S3


Right now we are at the stage when we need to stop using Hadoop cluster and as an alternative deep storage we are looking into S3.

We currently have about 2.5TB of data spread across 3 data sources gathered during several years and we cannot loose this data.

My question is what are all steps needed to be done so that Druid start to use S3 instead of Hadoop preserving all historical data?

Thank you!
