Steve Loughran commented on MAPREDUCE-319:
------------------------------------------

now that MRv2 uses netty for its shuffle, is this JIRA obsolete?

> As mentioned in HADOOP-1273 and references therefrom, Jetty 6 still doesn't seem to be stable enough for use in Hadoop. Instead, we've decided to consider the usage of Grizzly Framework [https://grizzly.dev.java.net/] for NIO based communication.
