Review request for Yongqiang He and Paul Yang.
Changes
-------
Added unit-test, also handled ChecksumException
Summary
-------
Sometimes it is useful to tolerate corruptions during a query and return
results based on the files that can be processed. A single corrupt block of
data should not prevent reading the rest of the data.
We need a way to gracefully ignore errors while reading a RC File
This addresses bug HIVE-2404.
