Subject Re: Figuring out when a job has successfully restored state
Date Wed, 29 Mar 2017 08:22:58 GMT
Hi Gyula,

there exists a related issue [1]. Fixing this issue will move the state
restoration in the state DEPLOYING. This means that when you see a task
being in state RUNNING, then it will have restored all of its eager state.

Cheers,
Till
