> Key: HDFS-13838
> URL: https://issues.apache.org/jira/browse/HDFS-13838
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: hdfs, webhdfs
> Affects Versions: 3.0.3, 3.1.0
> Reporter: Siyao Meng
> Assignee: Siyao Meng
> Priority: Major
> Attachments: HDFS-13838.001.patch, HDFS-13838.002.patch

>
> "Snapshot enabled" status has been added in HDFS-12455 by [~ajaykumar].
> However, it is found by [~jojochuang] that WebHdfsFileSystem.getFileStatus()
> won't return the correct "snapshot enabled" status. The reason is that
> JsonUtilClient.toFileStatus() did not check and append the "snapshot enabled"
> flag to the resulting HdfsFileStatus object.
> Proof:
> In TestWebHDFS#testWebHdfsAllowandDisallowSnapshots(), add the following
> lines indicated by prepending "+":
>
> {code:java}
> // allow snapshots on /bar using webhdfs
> webHdfs.allowSnapshot(bar);
> +// check if snapshot status is enabled
> +assertTrue(dfs.getFileStatus(bar).isSnapshotEnabled());
> +assertTrue(webHdfs.getFileStatus(bar).isSnapshotEnabled());{code}
>
> The first assertion will pass, as expected, while the second assertion will
> fail because of the reason above.
