Re: How hdp.version is calculated?

[Alejandro Fernandez <af...@hortonworks.com>]

A lot of services rely on how the process is started. It analysis its
current working directory to find the version of HDP from the path.
E.g.,
/usr/hdp/current/$component-name symlink to /usr/hdp/#.#.#.#-###/$component
/usr/hdp/#.#.#.#-###/$component/bin/start.sh

Thanks,
Alejandro
