Kihwal Lee created HDFS-8547: -------------------------------- Summary: The space reservation for RBW block is leaking Key: HDFS-8547 URL: https://issues.apache.org/jira/browse/HDFS-8547 Project: Hadoop HDFS Issue Type: Bug Reporter: Kihwal Lee Priority: Critical
HDFS-6898 added the feature to reserve space on datanode when creating RBW replicas. We have noticed that nonDfsUsed increasing on some of the datanodes. Heap dump of datanodes has revealed that {{reservedForRbw}} was huge (~90GB) for each volume. There weren't many rbw blocks at that time, so datanode must leaking it. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
