We have implemented a Hadoop compatible framework that helps in detection of suspected hardware failures in DataNodes within a Hadoop cluster and in signalling the nodes accordingly. Based on the status of the various hardware components of the DataNodes, the master node signals the DataNode so that appropriate actions can be taken. In a Hadoop cluster, the knowledge of the network is important for...
Migrating virtual machines (VM) at run time within acceptable time limits is significantly challenging due to large size of the virtual disk files. In this paper, we propose our framework called cloudspider to overcome this challenge by combining replication and scheduling of VM images into a common framework. In particular, we replicate VM images apriori onto a few chosen cloud sites and select one...
