Matt Burgess commented on NIFI-7516: ------------------------------------ It may be more trouble than it is worth to detect a singular matrix ahead of trying to make the predictions, I recommend just logging the issue at the debug level > Predictions model throws intermittent SingularMatrixExceptions > -------------------------------------------------------------- > > Key: NIFI-7516 > URL: https://issues.apache.org/jira/browse/NIFI-7516 > Project: Apache NiFi > Issue Type: Bug > Components: Extensions > Reporter: Matt Burgess > Priority: Major > > Under some circumstances, the Connection Status Analytics model (specifically > the Ordinary Least Squares model) throws a SingularMatrix exception: > org.apache.commons.math3.linear.SingularMatrixException: matrix is singular > This can happen (usually intermittently) when the data points used to update > the model form a matrix that has no inverse (i.e. singular). -- This message was sent by Atlassian Jira (v8.3.4#803005)
