This is an optimization, but nevertheless a low-hanging fruit , mostly
at toString() methods regarding the use of the right 'Appendable'
string. The build failures have nothing to do with the patch. Can
somebody review this. Thanks.

StringBuffer -> StringBuilder occurence
----------------------------------------
Key: MAPREDUCE-1320
URL: https://issues.apache.org/jira/browse/MAPREDUCE-1320
Project: Hadoop Map/Reduce
Issue Type: Improvement
Affects Versions: 0.20.1
Reporter: Kay Kay
Fix For: 0.20.2
Attachments: MAPREDUCE-1320.patch
A good number of toString() implementations use StringBuffer when the reference clearly does not go out of scope of the method and no concurrency is needed. Patch contains replacing those occurences from StringBuffer to StringBuilder.
Created against map/reduce project trunk .
