So, I think corncobs is not a utility, but a pattern - you have cron run curl to invoke something on your web application on the localhost (and elsewhere), and it runs the job if the job needs running, thus the webapp keeps the state.
There's a utility cronlock (https://github.com/kvz/cronlock) that runs on top of Redis. I was thinking that a common pattern would be something similar written in python using the kazoo module to dialog with zookeeper. No point writing much Java for a cronjob, but python should be OK. What I don't like about cronlock is that it isn't "run once", but instead avoids overlap, so there's good reason to write something specific to that case. -----Original Message----- From: Ahmet Arslan [mailto:iori...@yahoo.com.INVALID] Sent: Monday, August 31, 2015 1:35 PM To: solr-user@lucene.apache.org Subject: Re: DataImportHandler scheduling Hi Troy, I think folks use corncobs (with curl utility) provided by the Operating System.
