Hi HCFS Community :) This is Jay... Some of you know me.... I hack on a broad range of file system and hadoop ecosystem interoperability stuff. I just wanted to introduce myself and let you folks know im going to be working to help clean up the existing unit testing frameworks for the FileSystem and FileContext APIs. I've listed some bullets below .
- byte code inspection based code coverage for file system APIs with a tool such as corbertura. - HADOOP-9361 points out that there are many different types of file systems. - Creating mock file systems which can be used to validate API tests, which emulate different FS semantics (atomic directory creation, eventual consistency, strict consistency, POSIX compliance, append support, etc...) Is anyone interested in the above issues or have any opinions on how / where i should get started? Our end goal is to have a more transparent and portable set of test APIs for the hadoop file system implementors, across the board : so that we can all test our individual implementations confidently. So, anywhere i can lend a hand - let me know. I think this effort will require all of us in the file system community to join forces, and it will benefit us all immensly in the long run as well. -- Jay Vyas http://jayunit100.blogspot.com
