Here are couple of issues found one while starting traceserver and one
while getting the results in UI.
Currently the eclipse jetty version used is 8.1.7.v20120910
From main pom.xml
<jettyVersion>8.1.7.v20120910</jettyVersion>

When I changed the jetty version to 7.6.19.v20160209 it's working fine?
Aren't you facing it?
Once I do that again getting below exception and not able to read anything
from trace table.

Can we use the ObjectMapper from
org.apache.htrace.fasterxml.jackson.databind for the same purpose?
org.apache.htrace.fasterxml.jackson.databind.ObjectMapper available with HTrace
library included in Phoenix client jar. Otherwise getting above CNFE. It would
be better to fix these as well. WDYT?
> Tracing UI cleanup - final tasks before GSoC pull request
> ---------------------------------------------------------

> Key: PHOENIX-3193
> URL: https://issues.apache.org/jira/browse/PHOENIX-3193
> Project: Phoenix
> Issue Type: Improvement
> Reporter: Mujtaba Chohan
> Assignee: Nishani
>
> Points from GSoC presentation on tracing imporvements:
> *Tracing UI*
> * Remove line chart
> * In list page, run query with description, start_time, (end_time-start_time)
> duration from T where trace_id = ?
> * More space for descriptions on bar chart. Wrap if necessary
> * Label for X axis on timeline sometime again start from 0, if X axis is in
> seconds then it should not rollover after 60 seconds unless minutes are also
> shown
> * X-axis labeled as Node on various charts, but should be Percentage
> *Zipkin*
> * Flip zipkin chart on vertical axis with arrows going other way. So start
> from the top level root on the leftmost side and work toward children on the
> right.
> * Ask zipkin community if there's a way to tell it that date/time is in
> milliseconds.
> *Overall*
> * Please put together a pull request to the phoenix project to add the
> zipkiin work you've done to the OS project. Ideally, include the zipkin work
> in the phoenix-tracing module and call it phoeix-tracing. Only if there is
> some major hurdle, create a new module.
> * Test with trace_ids that have multiple spans with duration (end_time -
> start_time) > 5 ms and verify that UI and Zipkin output shows the correct
> corresponding timeline
