Chris Bevard created HADOOP-18706: ------------------------------------- Summary: The temporary files for disk-block buffer aren't unique enough to recover partial uploads. Key: HADOOP-18706 URL: https://issues.apache.org/jira/browse/HADOOP-18706 Project: Hadoop Common Issue Type: Improvement Components: fs/s3 Reporter: Chris Bevard
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. -- This message was sent by Atlassian Jira (v8.20.10#820010) --------------------------------------------------------------------- To unsubscribe, e-mail: common-issues-unsubscr...@hadoop.apache.org For additional commands, e-mail: common-issues-h...@hadoop.apache.org
