Subject [jira] [Commented] (HBASE-17261) Balancer makes no sense on tip of branch-1: says balanced when not
Date Sat, 04 Feb 2017 02:00:54 GMT

    [ https://issues.apache.org/jira/browse/HBASE-17261?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15852488#comment-15852488

Guanghao Zhang commented on HBASE-17261:

bq. I looked at HBASE-15529 but didn't see release note on which multiplier config to change
when minCostNeedBalance is set to a non-zero value.
The problem is default multiplier is too big. So we need change the multiplier config when
use minCostNeedBalance. I thought this config should only use for power user. We can first
make the default behavior same with before HBASE-15529. Then focus the probelm in HBASE-17565.
