Hi, I have a scenario where I have an existing cluster with all the services installed and started. I then add one or more slaves to the existing cluster.
I'm wondering if there' s an easy way for me to set the service/component states to INSTALLED then STARTED just for the new hosts? When installing the cluster I use something like PUT state=INSTALLED to /api/v1/clusters/c1/services?ServiceInfo/state=INIT, but obviously I can't use this on a running cluster. I've tried various predicates like selecting just the hostnames I need for a component, but the predicate isn't supported. For example, this fails /api/v1/clusters/c1/services/HDFS/components/DATANODE?host_components/HostRoles/host_name=my-hostname I know I can iterate through each host, but this is slow... Thanks in advance, Christian
