> Improve S3ABlockOutputStream recovery
> -------------------------------------
>
> Key: HADOOP-18706
> URL: https://issues.apache.org/jira/browse/HADOOP-18706
> Project: Hadoop Common
> Issue Type: Improvement
> Components: fs/s3
> Reporter: Chris Bevard
> Assignee: Chris Bevard
> Priority: Minor
> Labels: pull-request-available
> Fix For: 3.4.0
>
>
> If an application crashes during an S3ABlockOutputStream upload, it's
> possible to complete the upload if fast.upload.buffer is set to disk by
> uploading the s3ablock file with putObject as the final part of the multipart
> upload. If the application has multiple uploads running in parallel though
> and they're on the same part number when the application fails, then there is
> no way to determine which file belongs to which object, and recovery of
> either upload is impossible.
> If the temporary file name for disk buffering included the s3 key, then every
> partial upload would be recoverable.
> h3. Important disclaimer
> This change does not directly add the Syncable semantics which applications
> that require {{Syncable.hsync()}} to only return after all pending data has
> been durably written to the destination path. S3 is not a filesystem and this
> change does not make it so.
> What is does do is assist anyone trying to implement some post-crash recovery
> process which
> # interrogates s3 to identofy pending uploads to a specific path and get a
> list of uploaded blocks yet to be committed
> # scans the local fs.s3a.buffer dir directories to identify in-progress-write
> blocks for the same target destination. That is those which were being
> uploaded, queued for uploaded and the single "new data being written to"
> block for an output stream
> # uploads all those pending blocks
> # generates a new POST to complete a multipart upload with all the blocks in
> the correct order
> All this patch does is ensure the buffered block filenames include the final
> path and block ID, to aid in identify which blocks need to be uploaded and
> what order.
> h2. warning
> causes HADOOP-18744 -always include the relevant fix when backporting
