    Description

      To reproduce I used scrips from 5597.
      VM with 16cpu 16ram, 200GB disk.

      data amount:
      bash mock.bash edf_colstore vinci_cs_tracking_t 4000000 > tmp.sql; mariadb edf_colstore < tmp.sql;
      bash mock.bash edf_colstore pl_cs_contact_t 1000000 > tmp.sql; mariadb edf_colstore < tmp.sql;
      bash mock.bash edf_colstore pl_cs_question_t 1000000 > tmp.sql; mariadb edf_colstore < tmp.sql;
      bash mock.bash edf_colstore pl_cs_org_unit_t 1000000 > tmp.sql; mariadb edf_colstore < tmp.sql;
      bash mock.bash edf_colstore pl_cs_question_repository_t 1000000 > tmp.sql; mariadb edf_colstore < tmp.sql;
      bash mock.bash edf_colstore pl_cs_answer_repository_t 1000000 > tmp.sql; mariadb edf_colstore < tmp.sql;
      bash mock.bash edf_colstore pl_cs_tracking_status_t 1000000 > tmp.sql; mariadb edf_colstore < tmp.sql;

      Any other disk join exceeding disk space will be useful, I think.

      ERROR 1815 (HY000) at line 1: Internal error: DiskJoinStep::smallReader() Disk join could not write file /tmp/columnstore_tmp_files/joins//Columnstore-join-data-2293-small: No space left on device

      tmp files left in /tmp/columnstore_tmp_files for about 185GB after client disconnect
