---------------------------------
Summary: Group-By query on TPC-DS SF100 produces results but does
not terminate due to exception
Key: DRILL-2795
URL: https://issues.apache.org/jira/browse/DRILL-2795
Project: Apache Drill
Issue Type: Bug
Components: Execution - Flow
Affects Versions: 0.9.0
Reporter: Aman Sinha
Assignee: Jacques Nadeau
The following simplified group-by query with limit on TPC-DS SF100 eventually
produces results (the performance seems too slow for this scale factor) but
does not terminate. The log files show an IllegalStateException. I found that
after that first minute or so, all cpu's on the cluster show 99% idle time.
{code}
alter session set `planner.slice_target` = 100;
select cr_call_center_sk , cr_catalog_page_sk , cr_item_sk , cr_reason_sk ,
cr_refunded_addr_sk , cr_refunded_customer_sk from catalog_returns_dri100
group by cr_call_center_sk, cr_catalog_page_sk, cr_item_sk, cr_reason_sk,
cr_refunded_addr_sk, cr_refunded_customer_sk limit 10;
{code}
Cardinality of the table is relatively small:
{code}
0: jdbc:drill:schema=dfs.tpcds> select count(*) from catalog_returns_dri100;
