Subject [jira] Updated: (MAPREDUCE-1320) StringBuffer -> StringBuilder occurence
Date Wed, 30 Dec 2009 19:23:29 GMT

     [ https://issues.apache.org/jira/browse/MAPREDUCE-1320?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel
]

Todd Lipcon updated MAPREDUCE-1320:
-----------------------------------

    Affects Version/s:     (was: 0.20.1)
                       0.22.0
        Fix Version/s:     (was: 0.20.2)
                       0.22.0

Changing affects version to 0.22 - this is just a slight performance improvement, so shouldn't
be put on prior branches.

> 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 .
