Hi All,
We are migrating out topologies from 1.1.0 to 2.1.0. While doing so, if i
open the "show visualization" inside the topology details page i am seeing
nothing. When took network dump of the failing call, i see the logs
reported in the storm issue (STORM-2444
<https://issues.apache.org/jira/browse/STORM-2444>)
Although i see the issue has been marked as not-reproducible. can we
re-open it again.
Attaching the server error as attachment.

Thanks and regards,
Praveen Puskar
