Well, most of the tutorials i found on Oozie were written 2 or 3 years ago so i was wondering if it was still the recommended tech for this kind of things.

Hi @Lubin Lemarchand, for simple, single script, independent jobs you can also use cron. For jobs consisting of 2 or more scripts you can use Oozie which is the scheduling tool of choice in Hadoop ecosystem. Initially, Oozie didn't support Hive but now it does together with Pig, MR, Sqoop, Spark and other, so-called "actions" or steps. Long term, it's definitely worth learning more about Oozie: quick start.

you also invested time in learning nifi, nifi has a cron based scheduler, would be interesting to see it leveraged for this use case. Look under scheduling tab https://nifi.apache.org/docs/nifi-docs/html/user-guide.html#Configuring_a_Processor

Yes i use it to request the API i'm interested in once a week (except for the twitter streaming api of course).
