As a part of migration from CDH cluster to HDP cluster, we also had to migrate OpenTSDB which was running on CDH cluster. There are many methods to copy/transfer data between clusters and what we used here was ExportSnapshot.
So you are setting up HBase! Congratulations! When it comes to tuning HBase there are so many things you can do. And most of the things will be dependent upon type of data you will be storing and it’s access patterns. So I will be saying this a lot: ‘value of this parameter depends upon your workload’. Here I will try to enlist some of the variables that you can tweak while tuning hbase. This list is not at all exhaustive. Continue reading Stuff You Can Do While Tuning HBase
Currently I am working with new setup of Apache HBase cluster to query data using Phoenix on top of HDP Distribution. After setting up cluster, the values for heap, cache and timeouts were all defaults. Now I needed to know how good is the cluster in current shape and how can it be improved.
