[jira] [Commented] (HADOOP-7350) Use ServiceLoader to discover
compression codec classes
[ https://issues.apache.org/jira/browse/HADOOP-7350?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13207154#comment-13207154 ]
Alejandro Abdelnur commented on HADOOP-7350:
--------------------------------------------
Tom, thanks for reviving this one. Things look OK, the only thing is that I'd revert the logic to first load the codecs defined as services and after that the ones defined in Hadoop's configuration. By doing that, it is possible for a user to override a provided implementation.

> By using a ServiceLoader users wouldn't have to add codec classes to io.compression.codecs for codecs that aren't shipped with Hadoop (e.g. LZO), since they would be automatically picked up from the classpath.
