> 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.
