> Per the mailing list discussion and Rahul's and Paul's suggestion I'm filing this Jira
issue. Drill seems to be running out of memory when doing an External Sort. Per Zelaine's
suggestion I enabled sort.external.disable_managed in drill-override.conf and in the sqlline
session. This caused the query to run for longer but it still would fail with the same message.
> Per Paul's suggestion, I enabled debug logging for the org.apache.drill.exec.physical.impl.xsort.managed
package and re-ran the query.
> Here's the initial DEBUG line for ExternalSortBatch for our query:
