> Streaming's PipeMapper automatically ignores the key (LongWritable file offset) coming
from TextInputFormat. This is usually what the user wants, but occasionally the file offsets
are useful - for example, after grepping a large file for a particular pattern, you may want
to look at the offset in the file where the pattern matched. There should be a boolean configuration
variable which overrides ignoreKey in PipeMapper.java:86
