The overall installation process is:
Prepare the cluster.
Download and distribute packages.
Install CDAP services.
Start CDAP services.
Verify the installation.
Notes
Apache Ambari can only be used to add CDAP to an existing Hadoop cluster, one that already has the required services (Hadoop: HDFS, YARN, HBase, ZooKeeper, and—optionally—Hive and Spark) installed.
Ambari is for setting up HDP (Hortonworks Data Platform) on bare clusters; it can't be used for clusters with HDP already installed, where the original installation was not with Ambari.
A number of features are currently planned to be added, including:
select CDAP metrics and
a full smoke test of CDAP functionality after installation.
If you are installing CDAP with the intention of using replication, see these instructions on CDAP Replication before installing or starting CDAP.
