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. Thanks.
