Quick Links Disabled

[David McCauley <da...@wandisco.com>]

Hi,
I am having an issue with the 'Quick Links' menu 'greying out' within the
Services->HDFS page containing NameNode UI, logs etc. To reach this state
we have integrated it with our Non-Stop NameNode product which requires
HDFS with quite specific HA settings. These have quite possibly have
interfered with the standard HA setup, and may be a possible issue.

Unfortunately I am not a web developer by any means but I have tried to run
Ember Inspector on the page but it claims that an Ember application is not
detected. I am using version 1.3.1 and the latest Chrome if this helps.

If I could just get some suggestions on the problem or advice on how to
debug the issue that would be excellent, as no doubt there will be more
issues to diagnose. :)

Thanks in advance for any help,
Dave

Hi Yusaku,
I am using 1.5.1 at the moment, I have also used 1.6.0 and as you say the
links are not greyed out but only link to blank pages.

I think the problem lies in the fact that we have active-active NameNodes
with replication between them, Ambari is probably getting confused as a
result. From the screenshot as you can see we only display one of the
active NameNodes, the other two are alive and well but Ambari is unaware of
them.

If I could make Ambari just link to the primary NameNode that would
probably suffice for now. I'm going to look into the proper solution as we
progress.

Thanks very much!
Dave

Hi David,

What version of Ambari are you using?
My guess is that due to your setup, Ambari thinks both NameNodes are
in Standby (or not able to retrieve the active/standby status) and not
enabling the Quick Links.
Can you take a screenshot of what you are seeing?
In 1.6.0 and higher, you should always be able to access Quick Links
for NameNodes regardless of their active/standby state:
