Is the Hadoop scalability linear or proportional to number of nodes?

0 votes
Is it common to see this sentence: "Hadoop Scales Linearly". But, is there any performance evaluation to confirm this?

In my evaluations, Hadoop processing capacity scales linearly, but not proportional to a number of nodes, the processing capacity achieved with 20 nodes is not the double of the processing capacity achieved with 10 nodes. Is there any evaluation about this?
