xinyiZzz opened a new issue #5767:
URL: https://github.com/apache/incubator-doris/issues/5767


   **Describe the bug**
   For some large queries, after canceling the query in the mysql client, it 
takes a long time for the scan thread on be to completely exit. During this 
period, the I/O will be full.
   
   **To Reproduce**
   Table data Size: 12T, ReplicaCount: 4032.
   The query is similar: select * from T where c1 = xxx, where the value of xxx 
does not exist in column c1, so the entire table will be scanned.
   
   **Expected behavior**
   After the query was canceled during the running process, the actual be did 
not stop executing the query, which caused the I/O to be full.
