Description
The KuduClient allows setting a number of reactor threads, which are used for sending rpcs to Kudu such as for scans. Impala does not currently set this value, so it defaults to 4 threads, which may be too few for many use cases, since there is a single KuduClient per impalad. We should determine a better default (eg. based on the number of cpu cores) and also expose a flag to make it configurable.
