Brandon Li updated HDFS-7387:
-----------------------------
Affects Version/s: 2.6.0
> 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
> Components: nfs
> Affects Versions: 2.6.0
> 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.
