             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.
