Build broken: gerrit-verify-dryrun will likely crash

These two issues are causing frequent but non-deterministic crashes in Impala build+test runs (aka gerrit-verify-dryrun). Please refrain from running gerrit-verify-dryrun until the following issues are resolved. https://issues.apache.org/jira/projects/IMPALA/issues/IMPALA-6488

Re: PHJ node assignment

Jeszy, the way I read your question is: How much inter-node parallelism is good? As usual with perf question the answer is "it depends". Involving all nodes in the cluster for a PHJ may not work well. Intuitively, each node should have a minimum amount of work for the cost of shipping fragments

Re: Inconsistent float/double sort order in spec and implementations can lead to incorrect results

I hope the common cases is that data files do not contain these special float values. As the simplest solution, how about writers refrain from populating the stats if a special value is encountered? That fix does not preclude a more thorough solution in the future, but it addresses the common
