Nitay Joffe commented on HBASE-1144:
------------------------------------

Evgeny,

ZooKeeper does have access control lists that we can use to try to prevent
external clients from corrupting things. That said though, I think the whole
point of this is to get both the external clients and internal servers
coordinating through ZooKeeper rather than each other.

Perhaps Stack/JDCryans can elaborate further.

[jira] Updated: (HBASE-1144) Store the ROOT region location in Zookeeper

[ https://issues.apache.org/jira/browse/HBASE-1144?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ] Nitay Joffe updated HBASE-1144: ------------------------------- Attachment: hbase-1144-v2.patch Added parsing of conf/zoo.cfg to get clientPort/list of servers. If there are no server.X lines it is assumed that we are running our local ZooKeeper on the master server. Also updated the overview.html file. > Store the ROOT region location in Zookeeper > ------------------------------------------- > > Key: HBASE-1144 > URL: https://issues.apache.org/jira/browse/HBASE-1144 > Project: Hadoop HBase > Issue Type: Sub-task > Reporter: Jean-Daniel Cryans > Assignee: Nitay Joffe > Fix For: 0.20.0 > > Attachments: hbase-1144-v2.patch, hbase-1144.patch, overview.patch > > -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.

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. > Store the ROOT region location in Zookeeper > ------------------------------------------- > > Key: HBASE-1144 > URL: https://issues.apache.org/jira/browse/HBASE-1144 > Project: Hadoop HBase > Issue Type: Sub-task > Reporter: Jean-Daniel Cryans > Assignee: Nitay Joffe > Attachments: hbase-1144.patch, overview.patch > > -- This message is automatically generated by JIRA. - You can reply to this email to add a comment to the issue online.
