[jira] [Created] (AMBARI-11290) Avg Load for HBase is 261 regions per RS for a fresh one node cluster

Siddharth Wagle created AMBARI-11290:
----------------------------------------

             Summary: Avg Load for HBase is 261 regions per RS for a fresh one node cluster
                 Key: AMBARI-11290
                 URL: https://issues.apache.org/jira/browse/AMBARI-11290
             Project: Ambari
          Issue Type: Task
          Components: ambari-server
    Affects Versions: 2.1.0
            Reporter: Siddharth Wagle
            Assignee: Siddharth Wagle
             Fix For: 2.1.0


This happens because newer version of Phoenix sets salBuckets for sequence table to 256 creating 256 regions for salting by default.

We can add the above config to Ambari's computed values – anything smaller than 10 RS's should use a value of $numRs * 5. Something like this. It could be a hassle for folks who start small and add nodes; they'll need to split the table.
