Subject [jira] Commented: (HBASE-1144) Store the ROOT region location in Zookeeper
Date Tue, 27 Jan 2009 08:07:00 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1144?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12667617#action_12667617

Evgeny Ryabitskiy commented on HBASE-1144:

Am I right that you are going provide access for clients to ZK servers? Is it secure? 
As I understand ZK is like nervous system for distributed system, to share: configuration,
information about status for each nod, some massages about some events. For INTERNAL purposes
only. So may be we can even reduce all chatting between nods to sharing information in ZK.
It can be really nice :)
But clients are EXTERNAL, is it good to make external access to such sacred place as nervous
system of DB?

There is a problem that in HBASE-546 we are going to store in ZK information about which master
is active. So clients need in this information to get active master. May be we can just give
list of all possible masters (active and hot ready) for clients and they will try to find
active by sending requests.
