Description
**Is your feature request related to a problem? Please describe.**
Currently fail-over being developed Mars (#207) only supports one graph. However, support for fail-over in eager mode under a number of scenarios is quite useful.
**Describe the solution you'd like**
Support fail-over under eager mode, which may need re-execution of previous graph.
