Steve Loughran commented on HADOOP-15485:
-----------------------------------------

alternatively: once a stream read has succeeded once, it can't ever fail again.

Note that ti's the default "failure = 1.0f" value which is trouble here

> reduce/tune read failure fault injection on inconsistent client

> If you crank up the s3guard directory inconsistency rate to stress test the 
> directory listings, then the read failure rate can go up high enough that 
> things read IO fails,.
> Maybe  that read injection should only happen for the first few seconds of a 
> stream being created, to better model delayed consistency, or least limit the 
> #of times it can surface in a stream. (This woluld imply some kind of 
> stream-specific binding....)
> Otherwise: provide a way to explicitly set it, including disable
