Number of Maps = 10
Samples per Map = 100

The only error i could trace was in the nodemanager log file as below : ERROR org.apache.hadoop.yarn.server.nodemanager.NodeManager: RECEIVED SIGNAL 15: SIGTERM I tried checking various properties discussed in this thread, but i still have that issue. Can someone please help in solving this issue? Please let me know what all details i can provide.

Hi, I have not tried the 5.8 quickstart vm image till now, but if it asks for cluster details, then the options as shown on the screenshot are fine. Use the latest parcel, and if you don't need to experiment with different other connector parcels (you do not need to integrate with those systems) then you can safely leave those at None.

I deleted the VM (again), re-extracted the zip (again), in the terminal in the VM I run the script - sudo /home/cloudera/cloudera-manager --express --force (again), and this time I could log into Cloudera Manager with the credentials 'cloudera' and the cluster was already installed!

I loged into Cloudera Manager with username and password admin (beacuse the credentials 'cloudera' aren't working), and then I'm asked to " Specify hosts for your CDH cluster installation".
Shouldn't the cluster already be installed on Cloudera Quickstart VM?
