Owen O'Malley commented on ORC-310:

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?

>            Priority: Major
> 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.
