Text clustering has been developed in distributed system due to increasing data. The popular algorithms like K-Means (KM) and Fuzzy C-Means (FCM) are combined with Map Reduce algorithm in Hadoop Environment to be distributable and parallelizable. The problem is performance comparison between Distributed KM (DKM) and Distributed FCM (DFCM) that uses Tanimoto Distance Measure (TDM) has not been studied yet. It is important because TDM's characteristics are scale invariant while allowing

The result shows that DFCM-T has better intra-cluster and inter-cluster densities than those of DKM-T. Moreover, DFCM-T has lower processing time than that of DKM-T when total nodes used are 4 and 8. DFCM-T and DKM-T can perform clustering of 1,400,000 text files in 16.18 and 9.74 minutes but the preprocessing times take hours to complete.
