JiangHua Zhu created HDFS-16023: ----------------------------------- Summary: Improve blockReportLeaseId acquisition to avoid repeated FBR Key: HDFS-16023 URL: https://issues.apache.org/jira/browse/HDFS-16023 Project: Hadoop HDFS Issue Type: Improvement Reporter: JiangHua Zhu
When the NameNode receives the data (FBR) from the DataNode, it will put the data in the queue (BlockReportProcessingThread#queue), and there will be threads processing them thereafter. When the DataNode wants to send data (here, FBR) to the NameNode, it will first obtain a blockReportLeaseId from the NameNode. If the DataNode data already exists in the queue, there is no need to assign a blockReportLeaseId to the DataNode again. -- This message was sent by Atlassian Jira (v8.3.4#803005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
