> URL: https://issues.apache.org/jira/browse/HIVE-25001
> Project: Hive
> Issue Type: Improvement
> Components: Logging
> Affects Versions: 4.0.0
> Reporter: Chen Zhi
> Assignee: Chen Zhi
> Priority: Minor
> Labels: pull-request-available
> Fix For: 4.0.0
>
> Attachments: HIVE-25001.patch

> Time Spent: 1h

> Moving some potential expensive statements (e.g. `Arrays.toString`) into the
> adjacent logging guards, since these statements are merely used by the
> following logging calls.
> Note that the fix in `LlapTaskSchedulerService.java` is different with other
> cases in this patch, because the variable `requestedHostsDebugStr` is used by
> several debug-logging calls, and we have to declare and assign the variable
> before these debug-logging calls.
