Gelesh commented on HADOOP-8654:

Could you please share a Java Test file or a link to refer the same.
The confusion is, this error is inPut file based, and we need to supply a error case based
A link for the existing test case, which is as per the would help, which follows new the test
case rules as per Apache-wiki

> 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.hadoop@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
