Extensive logging of C++ application can slow down task by an order of magnitude
--------------------------------------------------------------------------------

                 Key: HADOOP-1553
                 URL: https://issues.apache.org/jira/browse/HADOOP-1553
             Project: Hadoop
          Issue Type: Bug
          Components: pipes
    Affects Versions: 0.13.0
            Reporter: Christian Kunz


We observed that extensive logging (due to some configuration mistake) of a c++ application
using the pipes interface can slow down the task by an order of magnitude. During that time
disk usage was not high, with no abnormal memory usage, and basically idle CPU.
