I have some basic questions on regions. 1) I have a 10 node HBase cluster. When I create a table in HBase, how many regions will be allocated by default? I looked at the HBase Master UI and it seems regions are not allocated to all the Regionservers by default. How can I allocate the regions in all Region Servers? Basically, This distributes the data in a better way If I am using a slated key. My requirement is to distribute the data across the cluster using salted keys. But, Having few regions is a constraint?
2) How does the rowkey to region mapping works? In Cassandra, we have a concept of assigning token range for each node. Rowkey will be assigned to a node based on the token range. How does this work in HBase? Regards, Arun
