Seems like with Hadoop 2.6.0 and HUE 3.9 with JobBrowser and HA Resource Manager there are two issues at hand see below.. 

At times it returns back nothing for applications is this expected to return a null... Which I can see if I hit refresh a few times in the job browser it goes and gets entire list of apps so not sure if this is a bug on the ResourceManager side or somewhere in the Hue javascript not calling the right URL??

ISSUE 1:

No data available is what I get in Hue until I hit refresh a bunch of times..

ISSUE 2:


I think the second issue still exists when under load... even with Romain's patch for cluster/info.. See below.. As both of these issues are very sporadic and seem to be triggered by using HA ResourceManager as this never happened until we enabled HA ResourceManager.. I think this problem is deep in kerberos_.py I am willing to help troubleshoot but need some guidance on what is being called when...

Hi Greg,

For Issue #2, we weren't actually able to reproduce this on a HA kerberized cluster.  What's odd is that you are receiving a 200 status code which would suggest that it's authenticating OK.  If you're able to troubleshoot, perhaps you can inspect the response in the handle_mutual_auth method: https://github.com/cloudera/hue/blob/master/desktop/core/ext-py/requests-kerberos-0.6.1/requests_kerberos/kerberos_.py#L181

Let us know if the response body yields any clues.  For Issue #1, we'll take a look, it could be a YARN bug that we need to add handling for.

For #1

When it works, what does it show in the logs?

When you curl:
/ws/v1/cluster/apps?limit=10000&user=greg&finalStatus=UNDEFINED

do you get {"apps":null} too?
Did you check the RM logs when we get {"apps":null} too?

Out from Curl:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?><apps/>

Rm Logs are clean.. no exceptions. I'm thinking we will need response body... IF you can pinpoint me to code base ill add some debug statements looks like urllib3 connectionpool?

Above is good, do yo have a run of logs where it is null then suddenly returning data? (there is no much you can print debug more, above lists the exact call made by Hue and show the first characters of the json response from the RM)
Did you check in the Chrome console if there was a js error in the page?

[31/Aug/2015 09:12:59 -0700] connectionpool DEBUG    "GET /oozie/v1/admin/status?timezone=America%2FLos_Angeles&user.name=hue&doAs=romain HTTP/1.1" 200 23
[31/Aug/2015 09:12:58 -0700] resource     DEBUG    GET Got response: {"apps":null}

For #2

If you modify
https://github.com/cloudera/hue/blob/master/desktop/core/ext-py/requests-kerberos-0.6.1/requests_kerberos/kerberos_.py#L181

that should be in
build/env/lib/python2.7/site-packages/requests_kerberos-0.6.1-py2.7.egg/
if you are using the non dev version of Hue

and
log.debug() a bunch of variables it should give more info.

Alternatively quick trying https://github.com/requests/requests-kerberos/issues/54 might help


Will try to repro one more time but Kerb YARN HA worked fine last time
