i check the debug log by grep balance,it show two type message: 1.[balancer.TableLoadBalancer] INFO : Loaded class org.apache.accumulo.server.master.balancer.DefaultLoadBalancer for table 2. [balancer.DefaultLoadBalancer] DEBUG: balance ended with 0 migrations there is no error or warn in the log and"Recent Logs" page. my question is that when i add a new tablet ,why accumulo do not process balance ? the new tablet server has no hosted table. 原始邮件 发件人:Josh [email protected] 收件人:[email protected] 发送时间:2014年12月21日(周日) 13:15 主题:Re: why the table not balance when i start a new tablet server Like Eric said, check the master_*.debug.log (grep for balance will probably show a reason why). Also, you should be able to see the same warning on the Accumulo monitor Recent Logs page. If you still cant find anything wrong looking at the logs, just restart the master process as a quick-fix. 覃璐 wrote: i see the master debug log ,but i not found error log. why a tablet offine not balancing?? the tablet 02 dead yet,and i restart it,but no table hosted in it. now i restart accumulo,i stop-all and start-all,why the tablet server not balance,the 04 no table. 原始邮件 *发件人:* Eric [email protected] *收件人:* [email protected][email protected]; [email protected] *发送时间:* 2014年12月20日(周六) 01:36 *主题:* Re: why the table not balance when i start a new tablet server If the master is not balancing, it will tell you why in the master debug log. Some reasons for not balancing: 1) a tablet server is not responding to status requests 2) a balance plan is already being executed 3) a tablet is offline -Eric On Fri, Dec 19, 2014 at 9:43 AM, John Vines [email protected] mailto:[email protected] wrote: The default load balancer tries to balance each table, so if you have several small (single tablet) tables, they will never be migrated since theyre currently balanced.
