Sergey Shelukhin commented on ORC-296:
--------------------------------------
[~gopalv] it's pretty rare. I think on the original workload we were hitting it
only on one buffer out of entire TPCH(?) set
> work around HADOOP-15171; also fix stream contract

> Stream read is never supposed to return 0 unless 0 bytes were requested, that
> breaks protobuf.
> The reason the streams can return 0 is that some buffers decompress to 0
> bytes due to HADOOP-15171.
