Or maybe more pessimistically, the second "stable" append implementation.
It's not like HADOOP-1700 wasn't intended to work. It was just found not to after the fact. Hopefully this reimplementation will succeed. If you're running a cluster that contains mission-critical data that cannot tolerate corruption or loss, you shouldn't jump on the new-feature bandwagon until it's had time to prove itself in the wild. But yes, we hope that appends will really-truly work in 0.21. Experimental/R&D projects should be able to plan on having a working append function in 0.21. - Aaron On Sun, Sep 20, 2009 at 3:58 PM, Stas Oskin <[email protected]> wrote: > Hi. > > Just to understand the road-map, 0.21 will be the first stable "append" > implementation? > > Regards. > > 2009/9/20 Owen O'Malley <[email protected]> > > > > > On Sep 13, 2009, at 3:08 AM, Stas Oskin wrote: > > > > Hi. > >> > >> Any idea when the "append" functionality is expected? > >> > > > > A working append is a blocker on HDFS 0.21.0. > > > > The code for append is expected to be complete in a few weeks.
