Steve Loughran commented on HADOOP-15088:
-----------------------------------------
Probably a common bug we've copied and pasted around. Why not add a new IOUtil
operation to do this, as other streams may do the same, especially the object
stores
> BufferedInputStream.skip function can return 0 when the file is corrupted,
> causing an infinite loop
