We recently started to use hadoop-0.20.1 in our production environment (less than 2 weeks ago) and already had 3 instances of truncated files, more than we had for months using hadoop-0.18.3.
Writing is done using libhdfs, although it rather seems to be a problem on the server side.
I will post some relevant logs (they are too large to be put into the description)
