Chen Zhang commented on HADOOP-15726: ------------------------------------- Hi [~xkrogen], the patch of this Jira only throttle log of write-lock, don't consider log of read-lock, any consideration here? > Create utility to limit frequency of log statements > --------------------------------------------------- > > Key: HADOOP-15726 > URL: https://issues.apache.org/jira/browse/HADOOP-15726 > Project: Hadoop Common > Issue Type: Improvement > Components: common, util > Reporter: Erik Krogen > Assignee: Erik Krogen > Priority: Major > Fix For: 2.10.0, 3.2.0, 3.0.4, 3.1.2 > > Attachments: HADOOP-15726.000.patch, HADOOP-15726.001.patch, > HADOOP-15726.002.patch, HADOOP-15726.003.patch, > HDFS-15726-branch-3.0.003.patch > > > There is a common pattern of logging a behavior that is normally extraneous. > Under some circumstances, such a behavior becomes common, flooding the logs > and making it difficult to see what else is going on in the system. Under > such situations it is beneficial to limit how frequently the extraneous > behavior is logged, while capturing some summary information about the > suppressed log statements. > This is currently implemented in {{FSNamesystemLock}} (in HDFS-10713). We > have additional use cases for this in HDFS-13791, so this is a good time to > create a common utility for different sites to share this logic. -- This message was sent by Atlassian Jira (v8.3.2#803003) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
