has it ever happened that a migration of persistent data has been needed (or automatically executed) when updating a Hadoop installation within a release?
If so, where could I find information regarding such needed migration?
I would be interested because the runtime of such migration would probably depend on the amount of managed data and had to be planned.
Thank you very much,
