[jira] [Commented] (HADOOP-11219) Upgrade to netty 4

    [ https://issues.apache.org/jira/browse/HADOOP-11219?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=14180806#comment-14180806 ] 

Haohui Mai commented on HADOOP-11219:
-------------------------------------

Please note that the upgrade can be done incrementally which reduces the risks.

Currently Hadoop uses netty 3, and netty 3 and netty 4 can coexist. The package of netty 3 and netty 4 are different ({{org.jboss.netty}} in netty 3 vs {{io.netty}} in netty 4). They have different artifact ids in the poms. Therefore the upgrade can be done incrementally.
