Subject hbase0.98.10 open region speed
Date Thu, 24 Sep 2015 08:33:20 GMT
in hbase 0.98.10,  we can set hbase to open region with or without zookeeper.
to compare open region speed of two ways, we perform a test
606 tables, 90683 regions
1 master, 3 regionservers

we get the open region speed from the log of master and regionservers
the result is as follows:

useZK: 5-7 min
notUseZK : 90 min

in the newer version of hbase, code of using ZK to open region are removed,
so, the open region speed will be slow down, is there any method to improve this?
