[jira] [Created] (ASTERIXDB-2611) Some aggregation queries fail when some partitions are empty

Ali Alsuliman created ASTERIXDB-2611:
----------------------------------------

             Summary: Some aggregation queries fail when some partitions are empty
                 Key: ASTERIXDB-2611
                 URL: https://issues.apache.org/jira/browse/ASTERIXDB-2611
             Project: Apache AsterixDB
          Issue Type: Bug
          Components: RT - Runtime
    Affects Versions: 0.9.4
            Reporter: Ali Alsuliman
            Assignee: Ali Alsuliman
             Fix For: 0.9.5


The below query fails if some partitions are empty. The cause is that the aggregator for empty partitions does not get the chance to produce a proper output because the nested plan pipeline is not opened.
{code:java}USE TinySocial;
WITH t AS 1
SELECT count(`friend-ids`), t
FROM FacebookUsers;{code}
