Subject [jira] [Commented] (YARN-4835) [YARN-3368] REST API related changes for new Web UI
Date Wed, 25 May 2016 18:22:12 GMT

    [ https://issues.apache.org/jira/browse/YARN-4835?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15300585#comment-15300585

Sunil G commented on YARN-4835:

bq.Initially I had thought this JIRA will cover all the REST changes including Sunil G's node
label related REST changes
After discussing with [~leftnoteasy], we thought its better to handle separately. 

bq.Should I include NM changes also in that JIRA or here ? We can atleast have Sunil's changes
here I guess.
I think we can have an MR jira to handle MR UI work. And in that, we can have the splitted
patch related to MR project. But its better this work happen in same branch eventhough its
a different jira (or umbrella jira in MR project).
My changes for node label can be done separate, and you can keep the NM webservice changes
here. (can change title a little bit)

bq.Regarding limiting log file size, we can probably add a query param to containerLogs endpoint
for number of bytes to return.
Do you mean an offset or some bytes to query for?

> Following things need to be added for AM related web pages.
> 1. Support task state query param in REST URL for fetching tasks.
> 2. Support task attempt state query param in REST URL for fetching task attempts.
> 3. A new REST endpoint to fetch counters for each task belonging to a job. Also have
a query param for counter name.
>    i.e. something like :
>   {{/jobs/\{jobid\}/taskCounters}}
> 4. A REST endpoint in NM for fetching all log files associated with a container. Useful
if logs served by NM.
