[jira] [Created] (HADOOP-14584) WASB to support high-performance commit protocol

             Summary: WASB to support high-performance commit protocol
                 Key: HADOOP-14584
                 URL: https://issues.apache.org/jira/browse/HADOOP-14584
             Project: Hadoop Common
          Issue Type: Sub-task
    Affects Versions: 3.0.0-alpha3
            Reporter: Steve Loughran


Once MAPREDUCE-6823 allows FileOutputFormat to take alternate committers, and HADOOP-13786 provides the first implementation and tests of a blobstore specific committer, WASB could do its own. The same strategy: upload uncommitted blobs and coalesce at the end should work; the same marshalling of lists of etags  *probably* work the same, though there will inevitably be some subtle differences.
