Lisheng Sun commented on HDFS-15172: ------------------------------------ [~elgoiri] I was intended to add this check In DeadNodeDetector#checkDeadNodes to prevent excessive frequency check. But waiting time has been added to idle() and every call to checkDeadNodes() will change the state to IDLE. So there will not is a situation that excessive frequency check. TestDeadNodeDetection#testDeadNodeDetectionDeadNodeRecovery() has covered about this change. Thank you. > Remove unnecessary deadNodeDetectInterval in > DeadNodeDetector#checkDeadNodes() > ------------------------------------------------------------------------------- > > Key: HDFS-15172 > URL: https://issues.apache.org/jira/browse/HDFS-15172 > Project: Hadoop HDFS > Issue Type: Sub-task > Reporter: Lisheng Sun > Assignee: Lisheng Sun > Priority: Major > Attachments: HDFS-15172-001.patch, HDFS-15172-002.patch > > > Every call to checkDeadNodes() will change the state to IDLE forcing the > DeadNodeDetector to sleep for IDLE_SLEEP_MS.
