Currently implementation of rand/random built-in functions use rand_r of C library. We recognized its randomness was poor. pcg32 of third party library shows better randomness than rand_r. Testing: Revise unit test in expr-test Add E2E test to random.test Change-Id: Idafdd5fe7502ff242c76a91a815c565146108684 Reviewed-on: http://gerrit.cloudera.org:8080/8355 Reviewed-by: Jim Apple <jbapple-impala@apache.org> Tested-by: Impala Public Jenkins
