DSE Cassandra decimal type
Since you're using Datastax Enterprise search nodes, solr is integrated with cassandra. What has happened here is that when you changed your solr schema, you did not change the associated cassandra schema. The error message is telling you that there is a mismatch between your new solr schema and the cassandra schema for the same table. Check the cassandra schema for seriesdata and make it consistent with the solr schema.
