[jira] [Created] (CRUNCH-626) HBaseSourceTarget Binary
compatibility across HBase versions
Micah Whitacre created CRUNCH-626:
-------------------------------------
Summary: HBaseSourceTarget Binary compatibility across HBase versions
Key: CRUNCH-626
URL: https://issues.apache.org/jira/browse/CRUNCH-626
Project: Crunch
Issue Type: Improvement
Components: IO
Reporter: Micah Whitacre
Currently Crunch targets HBase 1.0. Certain vendors however are trying to maintain API compatibility with HBase 0.96, 0.98, 1.0, and all 1.x.
While the API compatibility is ok across these versions, it was however not binary compatible as HBase changed the method signature from returning void[1] to returning OperationWithAttributes[1] (and in later versions Scan).
This results in an exception like the following, when you try to use the latest Crunch 0.14 release against that vendor's distribution of HBase which we should be theoretically compatible with.
