> Since there are users who are still using the old MR API, it will be useful to modify the org.apache.hadoop.mapred.LineRecordReader and org.apache.hadoop.mapred.TextInputFormat to be able to use custom (user-specified) end-of-record delimiters. This will make use of the LineReader improvement introduced in HADOOP-7096 that enables the LineReader to break lines at user-specified delimiters. 
> Note: MAPREDUCE-2254 already added this improvement to the new API (but not the old API).
