Konstantin Boudnik commented on HDFS-2136:
------------------------------------------
Todd, I find this
{{They're also easy to forget about since they're in a different tree, they're
slow to run, etc.}} to be a very interesting observation indeed ;) Especially
about the performance of the tests. Do you have any hard data to back this? I
would love to see how much slower an FI based test is compared to non-FI one?

> Both HDFS-1955 and HDFS-2135 have observed that it is difficult to unit test
> such failures. As a result, regression of HDFS-1955 was only found by
> careful manual review (thanks, atm!). Since 1073 is making broad changes to
> the way these files are read and written, and appropriately putting effort
> into correct error handling, I propose we make also make it possible to
> auto-test that error handling.
