Steve Loughran created HDFS-13936: ------------------------------------- Summary: multipart upload to HDFS to support 0 byte upload Key: HDFS-13936 URL: https://issues.apache.org/jira/browse/HDFS-13936 Project: Hadoop HDFS Issue Type: Sub-task Components: fs, hdfs Affects Versions: 3.2.0 Reporter: Steve Loughran Assignee: Ewan Higgs
MPUs to HDFS fail as you can't concat an empty block. Whatever uploads to HDFS needs to recognise that specific case "0-byte file" and rather than try and concat things, just create a 0-byte file there. Without this, you can't use MPU as a replacement for distcp or alternative commit protocols. -- This message was sent by Atlassian JIRA (v7.6.3#76005) --------------------------------------------------------------------- To unsubscribe, e-mail: hdfs-dev-unsubscr...@hadoop.apache.org For additional commands, e-mail: hdfs-dev-h...@hadoop.apache.org
