Steve Loughran commented on HADOOP-19076:
-----------------------------------------
[~fanningpj] makes sense. ideally we should strip out as much from
hadoop-common as possible. for example ssh support is only needed for people
using it for failover (org.apache.hadoop.ha). and the node fencing in hdfs and
yarn. and sftp filesystem which nobody seems to use much (nobody files bugs
against it...).

> Hadoop's Jersey dependencies are causing us real trouble.
> I'm wondering if it would be a good idea to take the jersey and javax.ws code
> out of hadoop-common and move it into a dedicated hadoop-jersey1-common jar.
> We could later create a hadoop-jersey2-common.
> hadoop-jersey1-common and hadoop-jersey2-common would have equivalent classes
> - just depend on different versions of Jersey.
> Example code:
> *
> https://github.com/apache/hadoop/blob/12498b35bbb754225b0b2ca90d5ad4f5cf628d56/hadoop-common-project/hadoop-common/src/main/java/org/apache/hadoop/http/HttpServer2.java#L1030

> Hadoop modules that need access to the common jersey code could start with
> depending on hadoop-jersey1-common but later be refactored to use
> hadoop-jersey2-common. We could do this on a module by module basis (one a
> time).
> hadoop-common jar would have its jersey and jsr311-api dependencies removed.
