This means that if you join a new regionserver to the cluster after startup, it does not get assigned a fair share of the already-served regions as you would expect. It only gets a share of new regions being served. > The master should periodically check the balance of regions, based on whatever assignment function, instead of in reaction to the above listed events. -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
