             Summary: 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


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. Exception thrown:
