Subject [jira] [Commented] (HADOOP-7323) Add capability to resolve compression codec based on codec name
Date Mon, 23 May 2011 23:50:47 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-7323?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13038326#comment-13038326

Tom White commented on HADOOP-7323:
-----------------------------------

This looks good. The only nit I noticed is that the javadoc on codecsByName in CompressionCodecFactory
is incorrect.

> When setting up a compression codec in an MR job the full class name of the codec must
be used.
> To ease usability, compression codecs should be resolved by their codec name (ie 'gzip',
'deflate', 'zlib', 'bzip2') instead their full codec class name.
> Besides easy of use for Hadoop users who would use the codec alias instead the full codec
class name, it could simplify how HBase resolves loads the codecs.
