Subject [jira] Commented: (HADOOP-6588) CompressionCodecFactory throws IllegalArgumentException
Date Tue, 23 Feb 2010 01:07:27 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-6588?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12837023#action_12837023
] 

Hong Tang commented on HADOOP-6588:
-----------------------------------

That is because you specified LzoCodec class in your conf file. I think it is better to leave
the behavior as-is instead of issuing log messages.
