> During a rolling upgrade, service components and clients call {{hdp-select}} to set the new version and update symlinks in {{/usr/hdp/current}}.
> There is a problem in that {{/usr/hdp/current/hadoop-client}} may never be run if there are non-HDFS/YARN/MapR clients installed on a host. Essentially, components always call 
> {noformat}
> hdp-select set oozie-client 2.2.1.0-1234
> {noformat}
> Where the component name is scoped correctly (falcon-client, etc)
> {{/usr/hdp/current/hadoop-client}} however does not have an associated client. Therefore, the 
> {{<group name="CLIENTS" title="Client Components">}} group in the upgrade pack should call the following:
> {noformat}
> hdp-select set client 2.2.1.0-1234
> {noformat}
