> Add Service Wizard corrupts the zookeeper config for existing Storm service
> ---------------------------------------------------------------------------
>
> Key: AMBARI-6472
> URL: https://issues.apache.org/jira/browse/AMBARI-6472
> Project: Ambari
> Issue Type: Bug
> Components: client
> Affects Versions: 1.6.1
> Reporter: Antonenko Alexander
> Assignee: Antonenko Alexander
> Priority: Critical
> Fix For: 1.6.1
>
> Attachments: BUG-20099_branch-1.6.1.patch, BUG-20099_trunk.patch
>
>
> STR:
> 1. On a cluster with Storm already installed, run Add Service Wizard to
> install an additional service not already part of the cluster (say, Falcon,
> but it doesn't matter which service).
> 2. Try to restart Storm. Nimbus/Supervisor will not be able to start
> Note that adding Storm itself via Add Service Wizard works fine.
> This corruption happens when adding a non-Storm service.
> The reason is Add Service Wizard updates storm-site and in doing so, corrupts
> *storm.zookeeper.servers* property.
> Before running Add Service Wizard:
> {noformat}
> storm.zookeeper.servers:
> "['c6401.ambari.apache.org','c6402.ambari.apache.org','c6403.ambari.apache.org']"
> {noformat}
> After completing Add Service Wizard to add another service:
> {noformat}
> storm.zookeeper.servers:
> "'['c6401.ambari.apache.org','c6402.ambari.apache.org','c6403.ambari.apache.org']'",
> {noformat}
> After completing Add Service Wizard again to add another service:
> {noformat}
> storm.zookeeper.servers:
> "''['c6401.ambari.apache.org','c6402.ambari.apache.org','c6403.ambari.apache.org']''",
> {noformat}
> Note that every time Add Service Wizard runs, extra single quotes are added
> around the ZK array.
> *Workaround*
> After running Add Service Wizard, go to Services > Storm > Config and hit
> Save. This fixes *storm.zookeeper.servers* and Nimbus/Supervisors will be
> able to start.
