Subject [jira] Commented: (HBASE-1329) Visibility into ZooKeeper
Date Tue, 21 Apr 2009 00:17:50 GMT

    [ https://issues.apache.org/jira/browse/HBASE-1329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12700996#action_12700996
] 

Patrick Hunt commented on HBASE-1329:
-------------------------------------

This reminds me, there's also the zk shell:

http://hadoop.apache.org/zookeeper/docs/current/zookeeperAdmin.html#sc_zkMulitServerSetup

see step 6, help is available inside the shell.

We'd be happy to work with you to refactor this if you'd like to embed it as part of your
own shell (perhaps refactoring is not even necessary, take a look). You could set it up to
run
any of the zk commands from your own shell by prefixing with "zk " ....

Could include the nc commands as well... although we've been talking about making things
like status available as r/o znodes...

>                 URL: https://issues.apache.org/jira/browse/HBASE-1329
>             Project: Hadoop HBase
>          Issue Type: New Feature
>    Affects Versions: 0.20.0
>            Reporter: Nitay Joffe
>
> Currently, to the users of HBase ZooKeeper is some mysterious thing that is for some
reason important but no one knows why. We need to provide more visibility into ZooKeeper from
HBase.
> This issue is to start a discussion on what sorts of things we can/should provide. Some
possible ideas to get started:
> - Running a REST server. See ZOOKEEPER-36.
> - FUSE support. See ZOOKEEPER-25.
> - Admin/surgery tools in HBase shell. Answer questions like "in safe mode?"
> - Status and information on HBase's data in ZooKeeper in the web UI.
