Shilun Fan updated HDFS-16090: ------------------------------ Affects Version/s: 3.3.2 3.4.0 > Fine grained locking for datanodeNetworkCounts > ---------------------------------------------- > > Key: HDFS-16090 > URL: https://issues.apache.org/jira/browse/HDFS-16090 > Project: Hadoop HDFS > Issue Type: Improvement > Affects Versions: 3.4.0, 3.3.2 > Reporter: Viraj Jasani > Assignee: Viraj Jasani > Priority: Major > Labels: pull-request-available > Fix For: 3.4.0, 3.3.2 > > Time Spent: 2.5h > Remaining Estimate: 0h > > While incrementing DataNode network error count, we lock entireĀ LoadingCache > in order to increment network count of specific host. We should provide fine > grained concurrency for this update because locking entire cache is redundant > and could impact performance while incrementing network count for multiple > hosts. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-issues-h...@hadoop.apache.org
