Andrew Wang commented on HDFS-7411:
-----------------------------------
bq. Is it the intended behavior?
Isn't it better that we can quickly mark all these nodes as decommissioned,
rather than waiting minutes or hours? I don't see why an admin would prefer
these nodes to stay decom-in-progress for hours. If anything, I hear admins
complaining about decom being too slow, never the opposite.
bq. Thanks for signing it up. What if you are unavailable later on? What if
there is a bug you don't know how to fix?
Well, Colin and Ming also reviewed this, so there are two more people who also
can help maintain. I can't comment on a hypothetical "bug you don't know how to
fix". Really these statements can be made about any patch.
Do you have specific requirements around additional testing? Or comments about
my proposals?
