-------------------------------------
Summary: Intermediate mem-to-mem: Fix early exit when only one
segment can fit into memory
Key: TEZ-3147
URL: https://issues.apache.org/jira/browse/TEZ-3147
Project: Apache Tez
Issue Type: Bug
Reporter: Rajesh Balamohan
Related to TEZ-1911 (since it got committed already, created this jira)
If there is only one segment left out in intermediate mem-to-mem merging, it
does an early exit. But before that it should add the segment back to
inMemoryMapOutput so that it can be considered for merging later.
