Following column families have to be created, Column family region has three column qualifiers: country, state, city, Column family Time has two column qualifiers: year, month. As we all know Hadoop is a framework written in Java that utilizes a large cluster of commodity hardware to maintain and store big size data. HBase tables are mainly divided into regions and are being served by Region servers. Where to use HDFS Whenever it receives a processing request, it forwards it to the corresponding node manager and . Handles load balancing of the regions across region servers. Consider we have row keys based on employee id, say from 1 to 10000. Methods and description Class HTable The Hadoop Distributed File System (HDFS) is a distributed file system for Hadoop.
