> Hi all,
> I’m working on a feature of the Hive WebUI Query Plan tab that would provide
> the option to display the query plan as a nice graph (scroll down for
> screenshots). If you click on one of the graph’s stages, the plan for that
> stage appears as text below.
> Stages are color-coded if they have a status (Success, Error, Running), and
> the rest are grayed out. Coloring is based on status already available in the
> WebUI, under the Stages tab.
> There is an additional option to display stats for MapReduce tasks. This
> includes the job’s ID, tracking URL (where the logs are found), and mapper
> and reducer numbers/progress, among other info.
> The library I’m using for the graph is called vis.js (http://visjs.org/). It
> has an Apache license, and the only necessary file to be included from this
> library is about 700 KB.
> I tried to keep server-side changes minimal, and graph generation is taken
> care of by the client. Plans with more than a given number of stages
> (default: 25) won't be displayed in order to preserve resources.
> I’d love to hear any and all input from the community about this feature: do
> you think it’s useful, and is there anything important I’m missing?
> Karen Coppage
