Zhihong Yu commented on HBASE-3373: ----------------------------------- Since the table name in the outer map is only used for grouping purposes, I think "ensemble" is a better name than "dummytable". The code snippets in second comment are equivalent. I may keep my code since this is patch 1 in a series of at least 3 patches. The other two are: block location affinity utilization and better load balancing heuristics for tables with presplit regions. > Allow regions to be load-balanced by table > ------------------------------------------ > > Key: HBASE-3373 > URL: https://issues.apache.org/jira/browse/HBASE-3373 > Project: HBase > Issue Type: Improvement > Components: master > Affects Versions: 0.20.6 > Reporter: Ted Yu > Fix For: 0.94.0 > > Attachments: 3373.txt, HbaseBalancerTest2.java > > > From our experience, cluster can be well balanced and yet, one table's > regions may be badly concentrated on few region servers. > For example, one table has 839 regions (380 regions at time of table > creation) out of which 202 are on one server. > It would be desirable for load balancer to distribute regions for specified > tables evenly across the cluster. Each of such tables has number of regions > many times the cluster size. -- This message is automatically generated by JIRA.
