Hanisha Koneru commented on HADOOP-14233: ----------------------------------------- Thank you [~jeagles]. The patch LGTM. It would be good to follow this practice for logging as well. Passing concatenated strings into a logging method can also incur a needless performance hit because the concatenation will be performed every time the method is called, whether or not the log level is set low enough to show the message. > Delay construction of PreCondition.check failure message in Configuration#set > ----------------------------------------------------------------------------- > > Key: HADOOP-14233 > URL: https://issues.apache.org/jira/browse/HADOOP-14233 > Project: Hadoop Common > Issue Type: Improvement > Reporter: Jonathan Eagles > Assignee: Jonathan Eagles > Attachments: HADOOP-14233.1.patch > > > The String in the precondition check is constructed prior to failure > detection. Since the normal case is no error, we can gain performance by > delaying the construction of the string until the failure is detected. -- This message was sent by Atlassian JIRA (v6.3.15#6346) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
