I am using HDP3 and ambari 2.7 to install a hadoop cluster. My blueprint does not have HBASE and it failed to be validated when I add it using ambari api:
"Cluster Topology validation failed. Invalid service component count: [HBASE_MASTER(actual=0, required=1+), HBASE_REGIONSERVER(actual=0, required=1+), HBASE_CLIENT(actual=0, required=1+)]. To disable topology validation and create the blueprint, add the following to the end of the url: '?validate_topology=false'"
I don't want to disable topology validation but can't figure out why HBASE is required by ambari validation.
