Assignee: Ke-Yi Sung
> Eliminate expensive string creation in debug log messages
> ---------------------------------------------------------
>
> Key: HDDS-5383
> URL: https://issues.apache.org/jira/browse/HDDS-5383
> Project: Apache Ozone
> Issue Type: Improvement
> Reporter: Wei-Chiu Chuang
> Assignee: Ke-Yi Sung
> Priority: Trivial
>
> Use IntelliJ and search with regex pattern: LOG\.debug.*toString
> I found a number of bad log message practice where string objects are created or concatenated regardless log level.
> Parameters passed to slf4j debug log are supposed to be O(1).
> For example,
> {code:title=KeyManagerImpl.refreshPipeline}
> } catch (IOException ioEx) {
> LOG.debug("Get containerPipeline failed for {}",
> containerIDs.toString(), ioEx);
> {code}
