Subject [jira] Commented: (HBASE-1124) Balancer kicks in way too early
Date Wed, 14 Jan 2009 08:22:59 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1124?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12663655#action_12663655

Andrew Purtell commented on HBASE-1124:
---------------------------------------

+1

Great patch, stack. Seems to work as advertised. Cluster comes up fast. I see some reassignment
activity toward the end but it's not like the churn before. I have ~500 regions now. All regions
are assigned out and opened before any HRS leaves safe mode and begins to compact/split.

> Balancer kicks in before all regions are assigned out. Causes confusion. Master won't
accept OPENs from "overloaded" HRS. Master is slow to respond to UI and HRS during. Master
sometimes takes too long to respond to a HRS heartbeat and so the HRS will reinit. This causes
more confusion.
