Sorry to interrupt, but I met an error "java.lang.NoClassDefFoundError: com/sun/jersey/api/client/config/ClientConfig"
in a secured environment after using this patch which is described in YARN-5271
I suppose this patch is conflicted with YARN-5271 and should still check for NoClassDefFoundError
in getTimelineDelegationToken method? 
Correct me if I miss something. Thank you.

> Yarn is implicitly trying to invoke ATS Client even though client does not need it. and
ATSClient code is trying to access hdfs. Due to that service is hitting GSS exception. 
> Yarnclient is implicitly creating ats client that tries to access Hdfs.
> All servers that use yarnclient cannot be expected to change to accommodate this behavior.
