Fixed a bug that was causing the pipes runner to incorrectly preprocess command line options.
Fixed several bugs triggered by using a local fs as the default fs for Hadoop. This happens when you set a file: path as the value of fs.default.name in core-site.xml. For instance:
<property>
<name>fs.default.name</name>
<value>file:///var/hadoop/data</value>
</property>
