[jira] Created: (HADOOP-6733) Create a test for FileSystem API
compatibility between releases

Project: Hadoop Common
Issue Type: Sub-task

--------------------------------------------
I believe the effort needs to go beyond FileSystem API.

-----------------------------------
I'm going to test this and MAPREDUCE-1637 by compiling and running a few simple programs (e.g. word count) against both 0.20.2 and 0.21.0. This will also get more testing as folks try out their programs against the 0.21.0 release candidates and the release.

Tom White commented on HADOOP-6733:
-----------------------------------
I totally agree, but we need to start somewhere. My hope is to have some basic sanity checks for compatibility which we can release 0.21 with. Over time I would hope that the API tests are built out to cover more of the codebase.

--------------------------------------------
This seems to be a very reasonable and sorta cheap approach of testing backward compatibility. The only thing needs to be kept in mind that set of test applications needs to be consistent from release to release. Otherwise, such verification won't be representative enough. But I guess word count doesn't go nowhere :)
