This repo is deprecated. Please see: scalding/maple

which now hosts the HBase, MemoryTap, and Etsy LocalTap. For JDBC, please see: Cascading-JDBC.

The reason for this deprecation is purely due to the manangement cost of the extra repo. If the old code meets your needs, there is little reason to upgrade.


A collection of useful Cascading taps.


Maple uses Leiningen 2.0 to build.

  1. lein with-profile dev deps
  2. lein with-profile dev uberjar
  3. lein with-profile dev install

The above should build a jar with all dependencies. And then install will add this jar to your local maven repository in ~/.m2/repositories.


Maple is hosted on Conjars. We expect most users will pull "com.twitter/maple" with the version they need. If you are submitting a patch, you will need to follow the above steps in Building.
