I don't think so, since calcite has some api changes when upgrade to 1.0+
version.
If you are just for demos, you can checkout the latest 0.7-staging branch
and build it.

Can I change the " optiq.version" in the pom.xml and build in
kylin-0.7.2 . It will work?

kylin use apache-calcite as its sql parser
and recently has upgraded calcite version to 1.3.0-incubating which support
window function.
however we have fully tested on this feature, it will be appreciated if you
test it on the new release
