ChiaPing Tsai updated HBASE-17194:
----------------------------------
Attachment: evaluation-v0.png
I evaluate the patch by ycsb. The flow is shown below.
# create a table (without pre-split)
# log the region distribution periodically
# put data via ycsb (recordcount=30000000)
> Assign the new region to the idle server after splitting

> The new regions are assigned to the random servers after splitting, but there
> always are some idle servers which don’t be assigned any regions on the new
> cluster. It is a bad start of load balance, hence we should give priority to
> the idle servers for assignment.
