Hey Costin,

If there are extra spaces left out, for instance, in the configuration below after the "${mapred.job.tracker}" token, the application fails. I believe it should have been trimmed out before being consumed by the framework code.
<hdp:configuration>
fs.default.name=${fs.default.name}
mapred.job.tracker=${mapred.job.tracker}
</hdp:configuration>

Can it be addressed?
