Matteo Bertozzi commented on HBASE-16520:
-----------------------------------------
I'd like this idea of forcing the owner. It should be on
ProcedureExecutor#submitProcedure() and not on load() so every proc will pass
from there as first operation.
the only problem with that is that now you also force tests to set an owner...
maybe we can have a flag like "check owner set" that we set to true by default
but in the test/resources/hbase-site.xml we set it to false. so the test will
not fail
> TableBackupProcedure ctor should set procedure owner
