> The ClusteredQuery API expects that all local indexes 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:

> Caused by: java.lang.NullPointerException
