    Description

      Probably originally thought as a feature, Hadoop-Pipes does not start a C++ reducer application when there are no key-values to be processed. Unfortunately, this does not allow to have certain common tasks performed by every reducer independent of key-value pairs. This is a requirement for our applications.
