Our system has single node impala cluster on top of 3 kudu nodes. As you can see the summary below, Exchange is taking too much time. I want to understand is this normal, or do I need to make any changes in Impala configurations.
It seems normal, I thing you have to increase the number of your Impala nodes to benifit of the magic MPP.. If you have 3 Kudu nodes, why you don't use 3 impala daemons? You can add the two in the same node.
