Build HUE RPMs: HDP_COMPONENT_VARIABLES.sh not found

I run the command
$ rpm2cpio hue-2.6.1.2.2.0.0-2041.el6.src.rpm | cpio -idv

and get
hue.init hue.init.suse
install_hue.sh
do-component-build
hue-2.6.1.2.2.0.0.tar.gz
hue.spec

then I following https://github.com/apache/bigtop/tree/master/bigtop-packages/src/rpm/hue folder schema, and put ‘hue.init hue.init.suse’ ‘install_hue.sh’ to SOURCES (also put hue-2.6.1.2.2.0.0.tar.gz), put ‘hue.spec’ to SPECS

after last step, I run
$ rpmbuild -bb hue.spec under SPECS

but error occurs as following
