> Ideally, the right value for this should have been closer to NDV * num_inst
384 is from 128 instances * 3 nodes.
The 128 comes from MAX_FRAGMENT_INSTANCES_PER_NODE constant.
https://github.com/apache/impala/blob/71818c673ba446c1f6a37a8181a74de02c09f7db/common/thrift/Query.thrift#L141-L143

This constant is the default value of query option 
MAX_FRAGMENT_INSTANCES_PER_NODE.
https://github.com/apache/impala/blob/71818c673ba446c1f6a37a8181a74de02c09f7db/common/thrift/Query.thrift#L671-L672
I will set lower option value for this test in future patch.
