Oozie is a workflow/coordination engine to orchestrate Hadoop jobs where Oozie Workflow jobs are Directed Acyclical Graphs (DAGs) of actions.
What are other Oozile like workflow engines to manage job chains on a cluster?
Is there a generic Oozile like workflow engine that is capable of orchestrating jobs any cluster through a plug-in or something?
although I personally prefer oozie you could also checkout azkaban.
