-----------------------------------------------------------

YARN currently does not have jcodings as a direct dependency. Copying from 
Rohith's comment above, this is what the dependency checker complains about
{code:java}
[INFO] — maven-enforcer-plugin:3.0.0-M1:enforce (depcheck) @ 
hadoop-yarn-server-timelineservice-hbase-client —
 [WARNING]
 Dependency convergence error for org.jruby.jcodings:jcodings:1.0.18 paths to 
dependency are:
 
+-org.apache.hadoop:hadoop-yarn-server-timelineservice-hbase-client:3.2.0-SNAPSHOT
 +-org.apache.hbase:hbase-client:2.0.0-beta-1
 +-org.jruby.jcodings:jcodings:1.0.18
 and
 
+-org.apache.hadoop:hadoop-yarn-server-timelineservice-hbase-client:3.2.0-SNAPSHOT
 +-org.apache.hbase:hbase-client:2.0.0-beta-1
 +-org.jruby.joni:joni:2.1.11
 +-org.jruby.jcodings:jcodings:1.0.13{code}

 So maven does see different versions. I suspect this is because the checker 
plugin only analyzes the pom tree without turning to maven dependency mediation 
mechanism.
