Change subject: IMPALA-3817: Ensure filter hash function is the same on all hardware. ...................................................................... IMPALA-3817: Ensure filter hash function is the same on all hardware. If some nodes in a cluster support the hardware CRC instruction, then those nodes would use that hash function when testing filters. This change uses Murmur2 always. Murmur2 is slower, but a perf run on a 16-node cluster showed negligible performance differences. (Also, remove unused hash function from HashUtil that was made dead code by an earlier commit.)
