Review request for hive, Peter Vary and Xuefu Zhang.
Bugs: HIVE-17300
https://issues.apache.org/jira/browse/HIVE-17300
Repository: hive-git
Description
-------
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.
