[jira] Created: (HBASE-1532) UI Visibility to ZooKeeper
UI Visibility to ZooKeeper
--------------------------
Key: HBASE-1532
URL: https://issues.apache.org/jira/browse/HBASE-1532
Project: Hadoop HBase
Issue Type: New Feature
Reporter: Nitay Joffe
Assignee: Nitay Joffe
Fix For: 0.20.0
Add ZooKeeper information/administration to UI.
Discussion showed particular interest in a tree-viewer application, something like ZOOKEEPER-418.
There was talk between Lars/JimK about how often the viewer should update its data.
See HBASE-1329 for more information.

[jira] Commented: (HBASE-1532) UI Visibility into ZooKeeper
Posted by "stack (JIRA)" <ji...@apache.org>.
[ https://issues.apache.org/jira/browse/HBASE-1532?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12720785#action_12720785 ]
stack commented on HBASE-1532:
------------------------------
For a start, how about we emit some basic zk info in the attributes table section at head of the master.jsp? (Perhaps quorum members?) Perhaps then, this value could be linkable. Clicking on the link would take you to a page that did a zk_dump. Refresh of page redid the zk_dump (I think this should be manual refresh -- not auto-refresh as we have in other pages).

Nitay Joffe commented on HBASE-1532:
------------------------------------
We already have a quorum members attribute at the head of the table. Yes, we can do as you suggest. I'll play around with doing that. Seems like it's worthwhile to wait until the ZK guys put ZOOKEEPER-418 in anyways?

Nitay Joffe commented on HBASE-1532:
------------------------------------
I had a possibly wild idea... Can we have the master set watches on parts of ZooKeeper the client is currently looking at in the viewer and then push the data to the client as events get triggered? HTTP is request-response though, so I suppose you always need to end up having some poll period so this is probably all moot.

I don't see the point of this line:
+ wrapper.getZooKeeper();
Otherwise +1.
