> Labels: feature_custom_service
>
> In Amabri 2.1.0 release, Ambari team added new client dependency check before
> adding/installing components based on JIRA
> https://issues.apache.org/jira/browse/AMBARI-10131. Based on this whenever we
> add new component to any hosts Ambari UI checks client dependencies defined
> in metainfo.xml file. If dependency clients not installed on same host then
> Ambari UI gives error and not allow install that component. Because of this
> even service for that client not installed, new Component not allowed to be
> installed.
> For example if HBase service not installed to the cluster and try to add
> custom component using Host Add action gives error that HBase client need to
> be installed prior to component install. This makes HBase client become a
> required client even though HBase service doesn't exist. Our custom component
> works without HBase we want to define HBase client as optional dependency.
> i.e if HBase service exist it should check for HBase client, other wise it
> should ignore HBase client exist check.
