Subject [jira] [Commented] (HADOOP-8262) Between mapper and reducer, Hadoop inserts spaces into my string
Date Mon, 09 Apr 2012 08:57:21 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8262?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13249742#comment-13249742
] 

Adriana Sbircea commented on HADOOP-8262:
-----------------------------------------

Hadoop is converting my string to Unicode. Those where not spaces, but Hadoop doesn't put
the encoding in the file, so I didn't know what where exactly. Today I have used a Hex Viewer
and there i saw that every character was converted to Unicode. I don't think it's ok.

> In the mapper i send as key a number, and as value another number which has more than
one digit, but i send them as Text objects. In my reducer all the values for a key have spaces
between every digit of a value. I can't do my task because of this problem. 
> I don't use combiners or something else.
