Subject [jira] [Commented] (HDFS-11427) Rename "rs-legacy" to "rs"
Date Sat, 18 Feb 2017 20:11:44 GMT

    [ https://issues.apache.org/jira/browse/HDFS-11427?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15873320#comment-15873320

Allen Wittenauer commented on HDFS-11427:
-----------------------------------------

History has shown that naming anything with "default" is extremely problematic when the default
needs to change. :(

> I think it's confusing (and verbose) that our RS code is named "rs-default" instead of
just "rs", partially because we also have the idea of setting a default implementation for
each codec. Let's rename it for simplicity.
> This is an incompatible change since it affects some configuration keys.
