Change subject: IMPALA-10519: Allow setting of num_reactors for KuduClient ...................................................................... IMPALA-10519: Allow setting of num_reactors for KuduClient The KuduClient allows setting a number of reactor threads, which are used for sending rpcs to Kudu such as for scans. The defaults is 4 threads, which may be too few for many use cases, since there is a single KuduClient per impalad. This patch adds a flag --kudu_client_num_reactor_threads which allows users to set the number of threads. The default for the flag is 16, which is consistent with the number of threads used in other IO scenarios such as --num_s3_io_threads and --num_ozone_io_threads. Some follow up work could be to do performance experiments and set the default empirically.
