> netty-all 4.1.1.Final is stable release which we should upgrade to.
> See bottom of HADOOP-12927 for related discussion.
> This issue was discovered since hbase 2.0 uses 4.1.1.Final of netty.
> When launching mapreduce job from hbase, /grid/0/hadoop/yarn/local/  usercache/hbase/appcache/application_1479850535804_0008/container_e01_1479850535804_0008_01_000005/mr-framework/hadoop/share/hadoop/hdfs/lib/netty-all-4.0.23.Final.jar
(from hdfs) is ahead of 4.1.1.Final jar (from hbase) on the classpath.
