TextInputFormat delimiter  bug scenario , a character sequence of the input text,  in which
the first character matches with the first character of delimiter, and reaming 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 condition 
1) contains the delimiter "record"
2) The character / character sequence immediately b4 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' ),

Hear the delimiter is skipped
