Good morning, I'm a student in computer science and I'm trying to use Hbase above an HDFS to show some performance of the system. I'd like to know how works the regionservers cluster when i insert / retrieve data from the cluster.
I have one master, one zookeeper server and 4 regionservers. I create a table and this is created only on one regionserver, in one specifically region. When I insert data, I notice that only that regionservers works, so i think the load is not splitted into the entire cluster. Is it right? Furthermore, when i retrieve data, again, only that regionserver still works. There is a way to split the data into different region on different regionservers? Because otherwise, i think there's no difference to have 1 or 4 regionservers but to have replication performed by HDFS. Hoping to has been clear, thank you in advance for your time, Andrea Gandini
