> Key: DRILL-8283
> URL: https://issues.apache.org/jira/browse/DRILL-8283
> Project: Apache Drill
> Issue Type: Improvement
> Components: Storage - Other
> Affects Versions: 1.20.2
> Reporter: James Turton
> Assignee: James Turton
> Priority: Minor
> Fix For: 1.20.3
>
>
> Currently a malicious, or merely an unwitting user can crash their Drill
> foreman by sending
> {code:java}
> select * from dfs.huge_workspace limit 10
> {code}
> causing the query planner to recurse over every file in huge_workspace and
> culminating in
> {code:java}
> 2022-08-09 15:13:22,251 [1d0da29f-e50c-fd51-43d9-8a5086d52c4e:foreman] ERROR
> o.a.drill.common.CatastrophicFailure - Catastrophic Failure Occurred,
> exiting. Information message: Unable to handle out of memory condition in
> Foreman.java.lang.OutOfMemoryError: null {code}
> if there are enough files in huge_workspace. A SHOW FILES command can produce
> the same effect. This issue proposes a new BOOT option named
> drill.exec.storage.file.max_listing_size with a default value of, say 10 000.
> If a file listing task exceeds this limit then the current operation is
> terminated with a UserException and runaway resource usage is prevented.
