Should I raise an issue for this?

Subject: Can't load a dependency (because I'm behind a proxy?)
Hi,
In a Zeppelin notebook I do this in the first paragraph:
%dep
z.reset()
z.load("com.quantifind:wisp_2.10:0.0.4")
- this appears to work ok when I run it (e.g., it says "Took 16 seconds")
But when I try this in a second paragraph:
import com.quantifind.charts.Highcharts._
The result is:
<console>:21: error: object quantifind is not a member of package com
import com.quantifind.charts.Highcharts._
So it looks like the dependency loading failed. Two points here:
1) I'm behind a corporate firewall. I was a bit alarmed to see
https://issues.apache.org/jira/browse/ZEPPELIN-169<https://urldefense.proofpoint.com/v2/url?u=https-3A__issues.apache.org_jira_browse_ZEPPELIN-2D169&d=BQMFAg&c=IV_clAzoPDE253xZdHuilRgztyh_RiV3wUrLrDQYWSI&r=c1CCNND4PG-Q_V2AJWDWrugZAXQ8Y3EE_f_mAHcpXcs&m=V9mNSM__4ymBHLerJcrBnKGaHALY_U_t9GspumiwMLo&s=Nf-0HxgMvYhvf899kda27ymRFJySv5VS2aZFhekOJvo&e=>
. Does this mean that it's impossible for me to fetch a dependency from behind
a proxy?! If not, please tell me how I can configure Zeppelin to use a proxy.
2) If z.load() fails (e.g., because it's behind a proxy!) it would be
great if it could report some kind of error message. Otherwise a user won't
know it's failed until they try running an import statement later on.
BTW I'm using zeppelin-0.5.0-incubating-bin-spark-1.3.1_hadoop-2.3.tgz
Thanks, Lucas.
