Description

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.

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;

Cardinality of the table is relatively small:

0: jdbc:drill:schema=dfs.tpcds> select count(*) from catalog_returns_dri100;
