Subject [jira] [Commented] (SPARK-833) Web UI's "Application Detail UI" link may use internal EC2 hostname
Date Sun, 30 Mar 2014 06:00:19 GMT


Patrick Wendell commented on SPARK-833:

I don't think there is a general way to fix this other than setting SPARK_PUBLIC_DNS in provisioning
frameworks such as the spark ec2 scripts and the amp camp scripts. AFAIK those have all been
updated to do this correctly, so I'm going to close this for now.

> In the new (0.8) web UI, the "Application Detail UI" link on the Application Info page
is derived from Utils.getLocalHostName().  When running on EC2, this link will break if the
local hostname isn't the public EC2 hostname.
> In SPARK-613, we fixed a similar problem by introducing a masterPublicAddress variable
that's populated from SPARK_PUBLIC_DNS if it's set.  We should probably do something similar
