https://community.cloudera.com/t5/Support-Questions/QuickStart-VM-requires-8-GB-of-RAM-My-Laptop-has-8GB-RAM-in/m-p/50995#M35491 Thanks a lot Cy Jervis for your response. Few questions if you could shade some light on: -<BR /><BR />I am specifically interested in Spark/Scala job development, specially aggregate functionality that Spark provides. Can I work with this in CDH 5 default mode ? since as per my understanding (which I am not very sure of) cloudera manager is the central service which controls all the services &amp; will only work in express or enterprise mode? Is there a workaround by which I can manage this?<BR /><BR />In General what is it that I can do in default mode? As documentation posted by cloudera only deals with express or enterprise mode<BR /><BR />Thanks a lot again for taking sometime out and responding to my query.
