Migration needed when updating within an Hadoop release
Hi,

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,
Björn
