Could be <String,Path> and save need for path conversion again in failedBulkLoad?

nit: origSources instead of origlSources?
There was a problem hiding this comment.
I left it like that because origPermissions uses String as well so a conversion would be done anyway. And while I could switch both of those to use Paths, log messages will need a string too.

Ok, let's just then follow var naming pattern, then.

One idea for FILE SFT, could we always force the copy option above, instead of this one that relies on rename?
There was a problem hiding this comment.
We could. My only concern is that it might be impractical over a certain data size especially if there is no config or param that would allow the user to use rename if they need to.
What do you think?
There was a problem hiding this comment.
True. My main concern is how safe this rename would be, if we don't have hboss in the picture. Could concurrent bulkloads be a problem in such cases? Maybe a workaround for such deployments would be to always pass a custom staging dir?
There was a problem hiding this comment.
I do not think concurrency is an issue. SecureBulkLoadListener keeps track of the moved files and a separate listener is created for each region in each bulkLoad. So even with parallel bulkLoads they can not touch each other's files. Using the same source folder can be an issue but it always was an issue.
I'm not sure I understand your comment about "always pass a custom staging dir". The staging dir by default is different for each bulkLoad process. I break this by introducing the "custom staging dir" which always points to the live data folder as a workaround to skip moving hfiles to an actual staging dir without loosing the existing error handling. We can't change it and decrease the number of moves at the same time.
There was a problem hiding this comment.
Ah, yeah, then we would need to rename from the custom stage to the actual dir anyways. I think we can leave it this way.
For S3 with SFT, I think the best practice would be to pass the copy option, for consistency. Shouldn't have much difference, as s3 renames are basically copies.
