ClusteredQuery throws NPE if any local index is empty ----------------------------------------------------- Key: ISPN-7837 URL: https://issues.jboss.org/browse/ISPN-7837 Project: Infinispan Issue Type: Bug Components: Embedded Querying Affects Versions: 9.0.0.Final Reporter: Gustavo Fernandes Assignee: Gustavo Fernandes The ClusteredQuery API expects all local index are populated with documents. With the setting Index.LOCAL, it's possible to index all documents in a single node (by only executing puts in this node), leaving all the other nodes empty.
