Bugs: AMBARI-14670
    https://issues.apache.org/jira/browse/AMBARI-14670


Repository: ambari


Description
-------

When upgrading HDP 2.2 to 2.4, the configurations for the 2.3 stack are not applied.

Caused by:

{code}
cat /grid/0/log/storm/storm.out

It appears as though {{nimbus.host}} was never converted to {{nimbus.seeds}} even though it's
defined in the upgrade pack:

{code}
<execute-stage service="STORM" component="NIMBUS" title="Apply config changes for Nimbus">
    <task xsi:type="configure" id="hdp_2_3_0_0_nimbus_convert_nimbus_host_to_seeds"/>
</execute-stage>
{code}

{code:title=HDP 2.2 storm-site}
"nimbus.host": "os-s11-3-hifgts-c10tom21unsecha-5.novalocal",
{code}

{code:title=HDP 2.4 storm-site}
"nimbus.host": "os-s11-3-hifgts-c10tom21unsecha-5.novalocal",
"nimbus.seeds": "localhost",
{code}
