Guocui Mi created HDFS-9787: ------------------------------- Summary: SNNs stop uploading FSImage to ANN once isPrimaryCheckPointer changed to false. Key: HDFS-9787 URL: https://issues.apache.org/jira/browse/HDFS-9787 Project: Hadoop HDFS Issue Type: Bug Components: ha Affects Versions: 2.6.2 Reporter: Guocui Mi
SNNs stop uploading FSImage to ANN once isPrimaryCheckPointer become false. Here is the logic to check if upload FSImage or not. In StandbyCheckpointer.java boolean sendRequest = isPrimaryCheckPointer || secsSinceLastUpload >= checkpointConf.getQuietPeriod(); doCheckpoint(sendRequest); The sendRequest is always false if isPrimaryCheckPointer is false giving secsSinceLast (~checkpointPeriod) >= checkpointConf.getQuietPeriod() (checkpointPeriod * this.quietMultiplier(default value 1.5)) always returns false. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
