>some task recompute before FAILED_TO_UNCOMPRESS happened
What's the meaning of this? From the code you changed, looks like this
corrupted file is happened in shuffle fetch, so what are you referring to "task
recompute", map task or reduce task?
Also it would be better to have a simple reproducible case to narrow down
the problem and fix it. Otherwise I don't think current fix is quite solid.
