AccessControlEnforcer is configurable. If an external AccessControlEnforcer runs for a long time to check permission with the FSnamesystem lock, it will significantly slow down the entire Namenode. In the JIRA, we will print a WARN message when it happens. -- 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
