Explanation: 

Detailed explanation-1: -K-Means which is one of the most used clustering methods and K-Means based on MapReduce is considered as an advanced solution for very large dataset clustering. However, the executing time is still an obstacle due to the increasing number of iterations when there is an increase of dataset size and number of clusters.

Detailed explanation-2: -The K-Means clustering algorithm fails to give good results when the data contains outliers, the density spread of data points across the data space is different, and the data points follow non-convex shapes.
