> I use streaming and in the perl-reducer I write to hdfs using  a pipe to hdfs -put -
....    It turns out that because TaskRunner sets the environment HADOOP_CLIENT_OPTS in double
quotes, when hdfs shell script concatenates these with something else, the command fails:
.e.g java -Dblah=x -Dfoo=y "-Dhadoop.tasklog.taskid=z -Dhadoop.tasklog.totalLogFileSize=s"...
> Since I don't see any reason to have these double quotes in the original code; I propose
they're removed.
