"address" values seem to be the same on b it's because of the "apt" field being null. Logical comparison will render the whole comparison as null which will render the comparison as false. This is inner join. https://asterix-gerrit.ics.uci.edu/#/c/3387/2/hyracks-fullstack/hyracks/hyracks-dataflow-std/src/main/java/org/apache/hyracks/dataflow/std/util/JoinUtil.java File hyracks-fullstack/hyracks/hyracks-dataflow-std/src/main/java/org/apache/hyracks/dataflow/std/util/JoinUtil.java: https://asterix-gerrit.ics.uci.edu/#/c/3387/2/hyracks-fullstack/hyracks/hyracks-dataflow-std/src/main/java/org/apache/hyracks/dataflow/std/util/JoinUtil.java@36 PS2, Line 36: public String printPartitionInfo(BitSet spilledStatus, OptimizedHybridHashJoin.SIDE whichSide, int numOfPartitions, > This method is specific to OptimizedHybridHashJoin, so why did we move into it's a debugging print which is not used in OptimizedHybridHashJoin. Having it there in production code isn't suitable, I think. But I can move it back if you see otherwise. If it's about the package, I can keep this Util class in the same package as the hybrid join.
