      Description

      With the new release 0.16.0 we experience extensive write failures under heavy load.

      The job shuffles 300TB on 1400 nodes and runs 3 waves of 2500 reducers. Each reducer uses libhdfs to write to around 70 dfs files simultaneously. We did not experience particular write problems up to nightly build #835 on hadoopqa (Jan 28),
      but now with released 0.16.0 (candidate 2) we see a lot of exceptions related to 'all datanodes are bad':

      typical exception(s):
