Subject [jira] [Commented] (HIVE-13467) Show llap info on hs2 ui when available
Date Sat, 23 Apr 2016 00:29:12 GMT

    [ https://issues.apache.org/jira/browse/HIVE-13467?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15254964#comment-15254964

Gunther Hagleitner commented on HIVE-13467:
-------------------------------------------

[~sseth] llap.html is static right now. It loads a JS file that will make a call to /llap
servlet to fetch the data. That makes it difficult to let you switch cluster view by changing
the url folks enter. I also think that if we need to support multiple clusters, we should
have a proper way to expose this on the UI. We can have a "Change cluster" input field on
the llap page. That way it's more straight forward for people to know what they're looking
at.

However, all that seems optional to me. The way to use llap right now is to set the instance
you're using in the config of your hs2. That's the one we'll display by default. If you have
multiple clusters, you'd have multiple hs2 instances likely anyways, no?

> When llap is on and hs2 is configured with access to an llap cluster, HS2 UI should show
some status of the daemons and provide a mechanism to click through to their respective UIs.
