I have a query. I am interested to know whether hadoop, mahout and spark, are all these included in cloudera manager or CDH or should I install them separately.
Please tell me how to install mahout,spark and hadoop on the same system.
These are all included in CDH since CDH 5.0.0. CDH 4 is missing Spark, but has the other 2. Hadoop and Spark can be managed by Cloudera Manager. Mahout has no server-side components and you will not see it in Cloudera Manager, but you can still run mahout jobs on the cluster. Mahout is just a client library.
