Erik Krogen resolved HDFS-13122. -------------------------------- Resolution: Duplicate > Tailing edits should not update quota counts on ObserverNode > ------------------------------------------------------------ > > Key: HDFS-13122 > URL: https://issues.apache.org/jira/browse/HDFS-13122 > Project: Hadoop HDFS > Issue Type: Sub-task > Components: hdfs, namenode > Reporter: Erik Krogen > Assignee: Erik Krogen > Priority: Major > > Currently in {{FSImage#loadEdits()}}, after applying a set of edits, we call > {code} > updateCountForQuota(target.getBlockManager().getStoragePolicySuite(), > target.dir.rootDir); > {code} > to update the quota counts for the entire namespace, which can be very > expensive. This makes sense if we are about to become the ANN, since we need > valid quotas, but not on an ObserverNode which does not need to enforce > quotas. > This is related to increasing the frequency with which the SbNN can tail > edits from the ANN to decrease the lag time for transactions to appear on the > Observer. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
