I am on my way for becoming a cloudera Hadoop administrator. Since my start, I am hearing a lot about computing slots per machine in a Hadoop Cluster like defining number of Map Slots and Reduce slots.
I have searched internet for a log time for getting a Noob definition for a Map Reduce Slot but didn't find any.
I am really pissed off by going through PDF's explaining the configuration of Map Reduce.
Please explain what exactly it means when it comes to a computing slot in a Machine of a cluster.
