------------------------------
Summary: DAG and Vertex commit should ensure that all tasks have
completed before committing
Key: TEZ-746
URL: https://issues.apache.org/jira/browse/TEZ-746
Project: Apache Tez
Issue Type: Improvement
Reporter: Bikas Saha
There may be a race when a task (say a speculative task) is still running. Then
the committer commits (say lists & cleans some files in the output dir). Then
that task writes some temporary files in the output dir and gets killed. Those
temp files may remain behind.
