> Key: HDFS-12952
> URL: https://issues.apache.org/jira/browse/HDFS-12952
> Project: Hadoop HDFS
> Issue Type: Bug
> Reporter: Sanjay Radia
> Assignee: Anu Engineer
>
> Currently Ozone KSM give visibility to a file only when the file is closed,
> which is similar to S3 FS. OzoneFs should allow partial file visibility as a
> file is being written to match HDFS.
> Note this should be fairly straightforward because the block-container layer
> maintains block length consistency as a block is being written even under
> failures due to its use of Raft.
