Hadoop performance Issues

Vote count:

I am doing a hadoop project where I am working with 100MB, 500MB, 1GB files. A multinode hadoop cluster with 4 nodes is implemented for the purpose. The time taken for running the mapreduce program in multinode cluster is much larger than the time taken in running single node cluster setup. Also, it is shocking to observe that the basic Java program(without hadoop) finishes the operation faster than both the single and multi node clusters.

Kindly mention as to what is the reason behind this anomaly.

P.S There are no issues with the configuration of the multinode hadoop cluster.
