Chu Tong commented on HADOOP-9692:
----------------------------------
There are two kinds of exception can be thrown here: IOException and
EOFException, and both of them are because of the file can't be read correctly.
Depending on how fine grind we want to go to, we can treat them both as file
reading error or only catch EOFException and throws IOException.
