Hi All - getting this error intermittently on a solr cloud cluster.
Sometimes the heatmap generation works, sometimes not. I tracked it
down to some of the nodes are reporting this error:

But that class is clearly present in the classpath in solr-core-8.2.0.jar. Any
idea how this is happening?
Thank you!
