I downloaded and started an instance of the HDP 2.4 as a VMWare sandbox. I just had a look for the directory structure, and found the there are the following 2 folders:
Why do I have two folders here as I didn't make any updates yet. I guess that the current folder is used for the platform tools like Spark etc. So if I need to update one of them (e.g. Spark) do I have to make the "changes" to that current folder or on both? Or will an update work completely different? Thank you!
/usr/hdp/current contains symlinks to versioned directories i.e. /usr/hdp/current points to /usr/hdp/2.4.0.0-169
