RandomSampleLoader does not handle skipping correctly in getNext()
------------------------------------------------------------------
Key: PIG-649
URL: https://issues.apache.org/jira/browse/PIG-649
Project: Pig
Issue Type: Bug
Affects Versions: types_branch
Reporter: Pradeep Kamath
Assignee: Pradeep Kamath
Fix For: types_branch
Currently RandomSampleLoader calls skip() on the underlying input stream
(BufferedPositionedInputStream) in its getNext(). The input stream may not
actually skip over the amount the RandomSampleLoader needs in one call.
RandomSampleLoader should check the return value from the skip() call and
ensure that skip() is called repeatedly (if necessary) till the needed number
of bytes are skipped.
