title: Is it possible to append to HDFS file from multiple clients in parallel?
body: <p>Basically whole question is in the title. I'm wondering if it's possible to append to file located on HDFS from multiple computers simultaneously? Something like storing stream of events constantly produced by multiple processes. Order is not important.</p>
  
  <p>I recall hearing on one of the Google tech presentations that GFS supports such append functionality but trying some limited testing with HDFS (either with regular file append() or with SequenceFile) doesn't seems to work.</p>
  
  <p>Thanks,</p>
