Amareshwari Sriramadasu commented on HADOOP-6439: ------------------------------------------------- Patch looks good. Some minor comments on the test: 1. Javadoc for the test needs modification. 2. Can you add some more comments on for the tests? 3. Can you extend testDeprecation for "set for M and get on N" and "set for Y and Z, get on X" ? > Shuffle deadlocks on wrong number of maps > ----------------------------------------- > > Key: HADOOP-6439 > URL: https://issues.apache.org/jira/browse/HADOOP-6439 > Project: Hadoop Common > Issue Type: Bug > Components: conf > Affects Versions: 0.21.0, 0.22.0 > Reporter: Owen O'Malley > Assignee: Owen O'Malley > Priority: Blocker > Fix For: 0.21.0, 0.22.0 > > Attachments: HADOOP-6439-1.patch, HADOOP-6439-2.patch, mr-1252.patch > > > The new shuffle assumes that the number of maps is correct.
