Jon Hemphill commented on CRUNCH-658:
-------------------------------------
I created CRUNCH-683 as a related issue that speeds up the getSize computation
by an order of magnitude when the source is S3.
> Add a way to skip the getSize checks for Sources from object stores

> Key: CRUNCH-658
> URL: https://issues.apache.org/jira/browse/CRUNCH-658
> Project: Crunch
> Issue Type: Bug
> Components: Core
> Affects Versions: 0.14.0
> Reporter: Josh Wills
> Assignee: Josh Wills
> Priority: Major
>
> Ran into a problem when using Crunch to process a _lot_ of data from S3: the
> getSize checks can be very slow to run and don't materially add much to the
> overall processing of a pipeline when things like reducer counts are manually
> specified. I'd like to add a way to disable the file size checks, either
> globally or for specific input sources.
