Change subject: IMPALA-5240: Allow configuration of number of disk I/O threads based on disk type ...................................................................... IMPALA-5240: Allow configuration of number of disk I/O threads based on disk type Currently Impala defaults to 8 threads per flash disk and 1 thread per rotational disk. This can be overridden with --num_threads_per_disk, but that sets the thread count independent of disk type. This would allow control of the number of disk I/O threads spawned independently for flash disks using "--num_threads_per_flash_disk" and for rotational disks using "--num_threads_per_rotational_disk" as startup parameters. Testing: Tested manually. Unfortunately, there is no way using DiskIoMgr class to confirm these variables were set, therefore no automated backend tests were added.
