Subject 答复: Detailed description of Zookeeper's role in Hbase system
Date Tue, 11 Mar 2014 07:20:14 GMT
A rough answer to this question (not necessarily comprehensive)

  1.  store root region's location
  2.  help select active master
  3.  help monitor regionservers' health
  4.  help table tasks such creating/deleting/enabling/disabling
  5.  help region-in-transition tasks such as assign/unassign/split/merge (store task status)
  6.  coordinate/dispatch hlog split tasks during regionserver failover
  7.  store replication configuration such as whether replication is enabled, peer configuration
and setting, and etc
  8.  store cluster-id

主题: Detailed description of Zookeeper's role in Hbase system

Can someone please direct me to good resources in understanding Zookeeper's
role in Hbase system ?
One in official guide does not explain it in detail.

Thanks and Regards,
