Subject [jira] Commented: (HADOOP-6659) Switch RPC to use Avro
Date Fri, 23 Apr 2010 11:25:00 GMT

eric baldeschwieler commented on HADOOP-6659:

Hi Doug,

I do not support an incremental approach of protocol porting. The idea  
of supporting parallel impementations of our current hdfs protocols is  
mind boggling, as you've told me several times during Hadoop's  

All of this change would be a huge tax on folks trying to stabilize  
Hadoop for release.

I agree doing this in a branch would be a huge job. This project is a  
huge job. That is my concern. It's not fair on the community to  
implicitly sign us all up to finish something of this scale. If you  
are signing up to do the project, great!  We will help you close once  
you can demonstrate you are close to the finish line.

I don't support throwing the whole community into a state where we  
need to finish this to ship good releases before anyone understands  
how we are going to finish it or who will finish it or how much work  
it will be.

Thanks for taking the time to understand my concerns!
