Rodrigo Schmidt commented on HDFS-1111:
---------------------------------------
I talked to Dhruba about this. Since we might want to extend this API in the
future, it sounds better to create a new return class.
@André: I thing using the class Boolean would work in centralized Java (no need
to create the array). Anyway, the RPC mechanism passes parameters by value as
far as I remember, which means we have to change the return class.
> getCorruptFiles() should give some hint that the list is not complete

> If the list of corruptfiles returned by the namenode doesn't say anything if
> the number of corrupted files is larger than the call output limit (which
> means the list is not complete). There should be a way to hint incompleteness
> to clients.
> A simple hack would be to add an extra entry to the array returned with the
> value null. Clients could interpret this as a sign that there are other
> corrupt files in the system.
> We should also do some rephrasing of the fsck output to make it more
> confident when the list is not complete and less confident when the list is
> known to be incomplete.
