Debian support for Presto Plugin #27

Open allanwilson opened 7 years ago

allanwilson commented 7 years ago

Installed Presto plugin for Ambari 2.4.2 on Debian 7. Running ambari as a non-root ambari user. Ambari user has all required sudo privs per Hortonworks Install Documentation for Ambari 2.4.2

Setting up the Presto service failed on these two steps: 1) mkdir /usr/lib/presto and required subdirs Worked around the above issue by manually creating the directories and setting ownership to the user ambari.

Most likely this is a support issue for Ambari running as non root. The install would've worked at this stage if the script issued a sudo in front of the mkdir commands (most likely).

2) Service install via Ambari failed installing Presto software Trying to install an rpm package 'presto-server-rpm-0.161.rpm' from /tmp. This is a Debian platform, so naturally this failed. Any support for Debian coming up?

I'll try installing the Presto software manually on our datanodes and see if that works.

Thanks

Unfortunately, I don't think anyone is actively working on this.

You could make the plugin work with an installation of Presto from tar.gz however you'll have to hack quite a few things. The RPM lays out start and stop scripts in /etc/init.d/ whereas the tar.gz doesn't. You'll have to edit the scripts in this repo's package/scripts directory. There are also probably other inconsistencies (that I can't remember now off the top of my head) between the two types of installations that will make this difficult. Also if you're editing the scripts live on a multinode cluster you'll have to delete the cached versions of the scripts on the worker nodes where the Ambari python agent is running so that your new versions get picked up.

Hope this helps!
