[jira] [Created] (DRILL-6998) Queries failing with "Failed to aggregate or route the RFW" due to "java.lang.ArrayIndexOutOfBoundsException" do not complete

Abhishek Ravi created DRILL-6998:
------------------------------------

             Summary: Queries failing with "Failed to aggregate or route the RFW" due to "java.lang.ArrayIndexOutOfBoundsException" do not complete
                 Key: DRILL-6998
                 URL: https://issues.apache.org/jira/browse/DRILL-6998
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - Flow
    Affects Versions: 1.16.0
            Reporter: Abhishek Ravi
            Assignee: weijie.tong
             Fix For: 1.16.0


Following query joins 2 tables on *two* (>1) fields.
{noformat}
select count(*) from lineitem l inner join partsupp p on l.l_partkey = p.ps_partkey AND l.l_suppkey = p.ps_suppkey
{noformat}

The query does not return even though Fragment 0:0 reports a state change from {{RUNNING}} -> {{FINISHED}}

Following is the jstack output of the {{Frag0:0}}.

From the code, it seems that {{RuntimeFilterSink.close}} is stuck at
{code:java}
    while (!asyncAggregateWorker.over.get()) {
      try {
        Thread.sleep(100);
      } catch (InterruptedException e) {
        logger.error("interrupted while sleeping to wait for the aggregating worker thread to exit", e);
      }
    }
{code}

This is because {{AsyncAggregateWorker}} exits due to the following exception, before it could set  asyncAggregateWorker.over is set to *false*.

{noformat}

A simple fix would be to add {{over.set(true)}} to the {{finally}} block of {{AsyncAggregateWorker.run}}.
