Gelesh commented on HADOOP-8654:
--------------------------------
I could write a Map Reduce, for testing
with the below code in Map Reduce Driver
Path inputDirectory = new Path("TestDirectory", "input");
Path file = new Path(inputDirectory, "InputFile.txt");
Writer writer = new OutputStreamWriter(localFs.create(file));
writer.write("The Reruired Very Big Input String"); // Fingers crossed
Path outFile = new Path(outputTestDirectory, "part-r-00000");
Reader reader = new InputStreamReader(localFs.open(outFile));
Is this okay ?

> TextInputFormat delimiter bug scenario , a character sequence of the input
> text, in which the first character matches with the first character of
> delimiter, and the remaining input text character sequence matches with the
> entire delimiter character sequence from the starting position of the
> delimiter.
> eg delimiter ="record";
> and Text =" record 1:- name = Gelesh e mail = gelesh.had...@gmail.com
> Location Bangalore record 2: name = sdf .. location =Bangalorrecord 3: name
> .... "
> Here string "=Bangalorrecord 3: " satisfy two conditions
> 1) contains the delimiter "record"
> 2) The character / character sequence immediately before the delimiter (ie '
> r ') matches with first character (or character sequence ) of delimiter. (ie
> "=Bangalor" ends with and Delimiter starts with same character/char sequence
> 'r' ),
> Here the delimiter is not encountered by the program resulting in improper
> value text in map that contains the delimiter
