Re: ZooKeeper gets three Google Summer of Code students
3 GSOC projects approved, that's great! Thank you students for applying for a project, should be some interesting new functionality/features developed over the summer. Thanks to all the mentors for stepping up and volunteering their time and Henry for shepherding the gsoc process (as well as being a mentor). I encourage our user base to engage with the students if they have interest in a particular project. If you have ideas, problems, or suggestions for features please discuss with the student (on the list is great). Exposing the mentees to how ZK based software is used in real life production environments will allow them to build a better product.

Andrei Savu will be working with Patrick Hunt on a Web-based Administrative Interface, extending and improving Patrick's Django-based front end. Abmar Barros will be working with Flavio Junqueira on improving ZooKeeper's failure detector module - making the code cleaner and easier to try out new implementations, as well as implementing a few failure detection algorithms himself! Finally, Sergey Doroshenko will be working with me on a Read-Only Mode for ZooKeeper, which will help bolster ZK's availability in certain circumstances when a network partition is detected, as well as potentially optimising the read-path. (The full list of 450 GSoC students is here: http://socghop.appspot.com/gsoc/program/list_projects/google/gsoc2010) Congratulations to all three - we look forward to seeing what you produce over the summer. Thanks to everyone who applied, suggested projects and offered to mentor students; this program will have a big effect on ZooKeeper's visibility and community, as well as hopefully producing some great code! cheers, Henry -- Henry Robinson Software Engineer Cloudera 415-994-6679
