[jira] Commented: (HBASE-1329) Visibility into ZooKeeper
[ https://issues.apache.org/jira/browse/HBASE-1329?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12700943#action_12700943 ]
Patrick Hunt commented on HBASE-1329:
-------------------------------------
Here's a couple more areas to investigate. Feel free to ask questions on one of our lists:
http://hadoop.apache.org/zookeeper/mailing_lists.html
These are commands that can be run against the server's command (client) port. They can
give insight into the status of the system:
http://hadoop.apache.org/zookeeper/docs/current/zookeeperAdmin.html#sc_zkCommands
Our JMX interface provides similar information:
http://hadoop.apache.org/zookeeper/docs/current/zookeeperJMX.html
A perl binding has been created, it's being integrated into 3.2 (avail on cpan):
https://issues.apache.org/jira/browse/ZOOKEEPER-378
We're working on a python binding and set of command line tools:

> Visibility into ZooKeeper
> -------------------------
>
> Key: HBASE-1329
> 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.
