---------------------------------
Summary: Add sequentialDo function for injecting arbitrary
non-parallel code
Key: CRUNCH-449
URL: https://issues.apache.org/jira/browse/CRUNCH-449
Project: Crunch
Issue Type: Bug
Components: Core
Reporter: Josh Wills
Assignee: Josh Wills
I've been noodling on this one for awhile: how to add the ability to execute
some code if and only if one or more targets are created, and have that
executed code (optionally) return one or more new PCollections as a result. I
was thinking that this functionality could be wired in to libraries to do
things like bulk loading HBase tables or running Sqoop jobs as part of Crunch
pipelines automatically.
