An Improved Data Placement Strategy in a Heterogeneous Hadoop Cluster
Hadoop Distributed File System (HDFS) is designed to store big data reliably, and to stream these data at high bandwidth to user applications. However, the default HDFS block placement policy assumes that all nodes in the cluster are homogeneous, and randomly place blocks without considering any nodes’ resource characteristics, which decreases self-adaptability of the system. In this paper, we ...
متن کاملAdaptive Dynamic Data Placement Algorithm for Hadoop in Heterogeneous Environments
Hadoop MapReduce framework is an important distributed processing model for large-scale data intensive applications. The current Hadoop and the existing Hadoop distributed file system’s rack-aware data placement strategy in MapReduce in the homogeneous Hadoop cluster assume that each node in a cluster has the same computing capacity and a same workload is assigned to each node. Default Hadoop d...
متن کاملIntelligent Block Placement Strategy in Heterogeneous Hadoop Clusters
MapReduce is an important distributed processing model for large-scale data-intensive applications. As an open-source implementation of MapReduce, Hadoop provides enterprises with a cost-efficient solution for their analytics needs. However, the default HDFS block placement policy assumes that computing nodes in a cluster are homogeneous, and tries to balance load by placing blocks randomly, wh...
متن کاملData Placement Strategy for Hadoop Clusters
Wireless technology has become very widely used; and an array of security measures, such as authentication, confidentiality strategies, and 802.11 wireless communication protocol based security schemas have been proposed and applied to real-time wireless networks. However, most of the measures only consider security issues in static mode, in which security levels are all configured when wireles...
