Jason Lowe updated HADOOP-8654:
-------------------------------
Release Note: (was: Dont find any incompatible changes and features.)
Hadoop Flags: (was: Reviewed)
Moving to project Hadoop Common since that's where the patch needs to be
applied.
In the future, please don't set the Reviewed flag unless the patch has been
reviewed and approved by someone in the community. I see no record of that
occurring, so I've cleared that flag. Also the Fix versions flag is intended
to mark where the patch has been integrated, please don't set this field. If
you'd like to indicate what versions you'd like to have the patch committed to,
use the Target Versions field.

> 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 = [email protected]
> 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
