[jira] [Created] (HBASE-10109) [0.89-fb] Balance #regions/RS better
when creating new table

--------------------------------------
Summary: [0.89-fb] Balance #regions/RS better when creating new table
Key: HBASE-10109
URL: https://issues.apache.org/jira/browse/HBASE-10109
Project: HBase
Issue Type: Improvement
Components: Region Assignment
Affects Versions: 0.89-fb
Reporter: Adela Maznikar
Assignee: Adela Maznikar
Priority: Minor
Fix For: 0.89-fb
When a new table is created we place the primary locations for the regions in a round robin fashion. Because we do this for every newly created table it is possible that some regionservers end up with more regions than the others and if there are more tables in the cluster the difference between a min and max #regions per RS can be larger.
One small optimization is to sort the RS in ascending order before assigning them regions.
