Dhruba, I'm working on making hdfs byzantine fault tolerant and was wondering if I have to account for current implementation of append. If all append semantic and design will be changed (as HADOOP-5744 indicated), I might have to wait for it to come out. If the change won't be significant, I will probably continue with current implementation.
Do you have any comment on this? Thanks, Sangmin On Mon, May 4, 2009 at 3:20 AM, Dhruba Borthakur <[email protected]> wrote: > The code for "append" is not supported in stable releases.
