Todd Lipcon updated HADOOP-6925:
--------------------------------
Attachment: hadoop-6925.txt
Patch fixes the read() implementation to correctly mask with 0xff before
upcasting to int. Also augments the unit test to check the single-byte read()
function - the new test fails before this patch.

> HADOOP-4012 added an implementation of read() in BZip2InputStream that
> doesn't work correctly when reading bytes > 0x80. This causes EOFExceptions
> when working with BZip2 compressed data inside of sequence files in some
> datasets.
