Filtering by Query with projection fails with ISPN028517 in the Remote Iterator

XMLWordPrintable

    • ER2

      The test that fails is in FilterByQueryProtoAnnotationSuite.scala from the jdg-spark connector:

        test("Filter by Query with projections") {
      val query = Search.getQueryFactory(remoteCacheManager.getCache(getCacheName)).from(classOf[Runner]).select("name", "age").having("finished").equal(true)
            .toBuilder.build()

      val rdd = createInfinispanRDD[Int, Runner].filterByQuery[Array[AnyRef]](query, classOf[Runner])
      val first = rdd.values.collect().head

      first(0).getClass shouldBe classOf[String]
      first(1).getClass shouldBe classOf[Integer]

      rdd.count shouldBe query.getResultSize
   }

      The Hot Rod client receives an error:

      java.lang.IllegalStateException: ISPN028517: The predicate org.infinispan.objectfilter.impl.syntax.parser.FilterExpressionBuilder$LazyLeafBooleanExpr@44bfa0bd can not be added since there may be only one root predicate.
