-------------------------------
Status: Patch Available (was: Open)
> Guaranteed NPE in StatsRulesProcFactory
> ---------------------------------------
>
> Key: HIVE-8576
> URL: https://issues.apache.org/jira/browse/HIVE-8576
> Project: Hive
> Issue Type: Bug
> Reporter: Lars Francke
> Assignee: Lars Francke
> Attachments: HIVE-8576.1.patch
>
>
> Code looks like this:
> {code}
> private List<Integer> getPrimaryKeyCandidates(List<Operator<? extends
> OperatorDesc>> ops) {
> List<Integer> result = Lists.newArrayList();
> if (ops != null || !ops.isEmpty()) {
> for (int i = 0; i < ops.size(); i++) {
> {code}
> The {{||}} should be {{&&}} as the current {{if}} statement can be rewritten
> as {{!(ops == null && ops.isEmpty())}} which doesn't make sense.
> Or am I missing something?
