why i am not able to echo these enviornment variables?

[#1]

I am not able to eacho $PARCELS_ROOT or CDH_HADOOP_HOME or HADOOP_CLASSPATH that looks like cm-defined environment.

Are they setup by clouder manager using parcels?

I am trying to extend my parcel to CDH hadoop classpath, how to get all cm-defined enviornment variables?
