Description

Currently, when JT is restarted , it does not remember any TT(s) which was blacklisted across the cluster before the restart. It would be useful if a new feature could be added for JT to remember blacklisted TT(s) even after restart. This would avoid JT from assigning tasks to faulty TT(s) each time after restart.
