---------------------------------
Summary: UI interaction very sluggish with more HDFS and HBase
processors on the graph
Key: NIFI-1698
URL: https://issues.apache.org/jira/browse/NIFI-1698
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 0.6.0
Reporter: Joseph Witt
Assignee: Bryan Bende
Priority: Critical
There is a very noticeable slow-down that is more obvious on slower
systems/clusters when more and more HDFS processors exist or when more and more
HBase processors exist. If they are enabled or running then it can cause
tremendous slowdowns in response time by a multiple of 2-10x. This in turn
leads the UI to be unresponsive.
