             Summary: S3A committers: make sure there's regular progress() calls
                 Key: HADOOP-15961
                 URL: https://issues.apache.org/jira/browse/HADOOP-15961
             Project: Hadoop Common
          Issue Type: Sub-task
          Components: fs/s3
            Reporter: Steve Loughran


MAPREDUCE-7164 highlights how inside job/task commit more context.progress() callbacks are needed, just for HDFS.

the S3A committers should be reviewed similarly.

At a glance:

StagingCommitter.commitTaskInternal() is at risk if a task write upload enough data to the localfs that the upload takes longer than the timeout.

it should call progress it every single file commits, or better: modify {{uploadFileToPendingCommit}} to take a Progressable for progress callbacks after every part upload.
