-----------------------------------
Summary: Topology visualization breaks when ':transferred' in
executor stats doesn't have any informations
Key: STORM-2335
URL: https://issues.apache.org/jira/browse/STORM-2335
Project: Apache Storm
Issue Type: Bug
Components: storm-core
Reporter: Jungtaek Lim
When opening Topology Visualization, below error is shown to the console of
browser:
{code}
visualization.js:314 Uncaught TypeError: Cannot read property 'default' of
undefined
at gather_stream_count (visualization.js:314)
at Object.<anonymous> (visualization.js:117)
at Node.<anonymous> (arbor.js:35)
at Function.each (jquery-1.11.1.min.js:2)
at Object.eachNode (arbor.js:35)
at Object.redraw (visualization.js:114)
at screenUpdate (arbor.js:33)
{code}
This is due to the fact that some executors doesn't have stats for
':transferred'.
Below is the part of API response, and you can see some executors are having
children for ':transferred' whereas others are not having children.
{code}
