Hbase regionserver.MultiVersionConcurrencyControl Warning

Hi, I'm currently testing Hbase 1.2.1 + OpenTSDB. For that, I'm generating a high load of HTTP PUT on OpenTSDB, which then writes in Hbase. Currently, I'm able to feed 300k data point per seconds, and I'm trying to achieve higher speed. I have also activate JMX on both Master and Region servers
