Unable to connect to Cassandra cluster

Suggest edit Updated on March 11, 2021

A node cannot join the Decision Data Store (DDS) cluster.

This issue is caused by the failure of a DataStax driver. An error message is displayed in Pega Platform when trying to add a node to the cluster, for example:

[JAVA-1220] Driver should fail fast on subsequent connect/init calls if Cluster.manager.init() fails - DataStax
java.lang.IllegalArgumentException: initialArraySize cannot be negative but was: -2147483648
