[jira] [Updated] (HADOOP-5814) NativeS3FileSystem doesn't report progress when writing

     [ https://issues.apache.org/jira/browse/HADOOP-5814?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

Subroto Sanyal updated HADOOP-5814:
-----------------------------------

    Attachment: HADOOP-5814.patch

The patch is on the trunk version.
The patch creates a input Stream which handles the Progressable reference and makes the call periodically while reading from the underlying stream. The patch is tested in our cluster and works fine.

> This results in timeouts since the whole file is uploaded in the close method. See http://www.mail-archive.com/core-user@hadoop.apache.org/msg09881.html.
> One solution is to keep a reference to the Progressable passed in to the NativeS3FsOutputStream's constructor, and progress it during writes, and while copying the backup file to S3 in the close method.
