Subject [jira] Commented: (HADOOP-6323) Serialization should provide comparators
Date Thu, 22 Oct 2009 20:14:59 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12768860#action_12768860
] 

Hong Tang commented on HADOOP-6323:
-----------------------------------

Makes sense.

On a side note, I wonder if we could extend this pattern to support raw comparator creation
in general. Currently, both TFile and mapreduce creates raw comparators using comparator class
names. In mapreduce's case, the comparators are created through ReflectionUtil, so in some
way, you can pass more information through the Configuration object.
