Sorry, I'm just getting back to this. 

So the problem is that the Hadoop codec doesn't properly reset() and needs to be removed from the pool?

Is it the DirectDecompressor? Snappy? Zlib?

I assume the AirCompressorCodecs aren't broken.

> When there's a failure potentially involving the codec, the codec object may be left in bad state and should not be reused (esp. given that Hadoop codecs are brittle w.r.t. how they maintain state).
> The codecs can be closed on error instead.
