HBase Load Balancing Algorithm Analysis and Improvement

As the Hadoop distributed open source database, HBase gradually gained a lot of attention due to its high-performance. However, with a large amount of data pouring into HBase, the situation of load distribution by HBase will directly affect the performance of the whole cluster. With the problem of load seriously imbalances in the process of original algorithm, proposed a novel load-balancing approach based on the limited child table, with the analysis of original algorithm and the causes of the problem. The contrast experiment showed that the improved approach of scheduling can make effective use of each node resources in the cluster, thereby improved the performance of the distributed cluster.
