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.
