Brandon Li created HDFS-7387: -------------------------------- Summary: NFS may only do partial commit due to a race between COMMIT and write Key: HDFS-7387 URL: https://issues.apache.org/jira/browse/HDFS-7387 Project: Hadoop HDFS Issue Type: Bug Reporter: Brandon Li Assignee: Brandon Li Priority: Critical
The requested range may not be committed when the following happens: 1. the last pending write is removed from the queue to write to hdfs 2. a commit request arrives, NFS sees there is not pending write, and it will do a sync 3. this sync request could flush only part of the last write to hdfs 4. if a file read happens immediately after the above steps, the user may not see all the data. -- This message was sent by Atlassian JIRA (v6.3.4#6332)
