Review request for Ambari, Nate Cole and Tom Beerbower.
Bugs: AMBARI-9160
https://issues.apache.org/jira/browse/AMBARI-9160
Repository: ambari
Description
-------
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}

Testing
-------
Manual test of upgrading a cluster with lots of services and clients; verifed
that hadoop-client symlink was correct on all hosts
