And the tool will make sure that the region number is large than the number of the regionserver and the regions will be distributed onto all regionservers. > Periodically, the tool will put data to these regions to calculate the write availability of HBase and send alerts if needed. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
