[jira] [Commented] (FLINK-5895) Reduce logging aggressiveness of FileSystemSafetyNet

["Stephan Ewen (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/FLINK-5895?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15880619#comment-15880619 ] 

Stephan Ewen commented on FLINK-5895:
-------------------------------------

This is a good example of why logging inside utility methods is often tricky. It is better to log in the classes that invoke the utilities, because they have the context to see whether and on what level the operation should be logged.

> The {{FileSystemSafetyNet}} logs on info level every time it is created and destroyed. This causes a log flood from the async checkpoint thread, which starts and stops that safety net very often.
