@ronaldgames could you please share the YAML configuration you're using?

[utsengar]

I am getting the same error. I am using local_scheduler_nozk.yml (the default config).
mesos built correctly as well as chronos. Any suggestions?

[utsengar]

Never mind, figured it out. Had to replace libmesos.dylib with libmesos-0.12.0.so in the startup script since I am running ubuntu.

[ronaldgames]

It works for me too, thanks. (Using local_scheduler_nozk.yml (the default config)).

[rmontagne]

Hello,

I have the same problem, but i can't use the local_scheduler_nozk.yml but he don't save the jobs when restarting the server. Please can you explain how can i solve this problem ?

Thanks,
Romain Montagne

[utsengar]

@rmontagne Use zookeeper with chronos to save the jobs after restarts. I think the config is: local_scheduler.yml. Side tracking, but if you are looking for a cron alternative with retries etc, we settled for azkaban by linkedin. It was much simpler and easier to manage.

[rmontagne]

Thx, have you a documentation or a link for saved cron with zookeeper ??, beacause azkaban rest API seems not complete.
Thx you very much.

[utsengar]

Just run a zk instance locally and then start chronos on the same node with this config file: https://github.com/airbnb/chronos/blob/master/config/local_scheduler.yml

Your data will be persisted.

This config you are currently using clearly says it won't persist it: https://github.com/airbnb/chronos/blob/master/config/local_scheduler_nozk.yml

And yes, the azkaban rest api has has some limitations, but you can upload and execute jobs via api in azkaban.

[rmontagne]

Thx all run good, it's ok for me ;)
