Description

The substitution feature i.e X=$X:/tmp doesnt work as expected.

This issue completes the feature mentioned in ~~HADOOP-2838~~. ~~HADOOP-2838~~ provided a way to set env variables in child process. This issue provides a way to inherit tt's env variables and append or reset it. So now
X=$X:y will inherit X (if there) and append y to it.
