Gopal V commented on TEZ-2850: ------------------------------ [~jeagles]: good call on the in == null check, that's a valid assumption for InMemoryReader. I notice that there's some possibility of an NPE in close() if checksSumIn is null, but I'm pretty sure it doesn't called in the normal operations. > Tez MergeManager OOM for small Map Outputs > ------------------------------------------ > > Key: TEZ-2850 > URL: https://issues.apache.org/jira/browse/TEZ-2850 > Project: Apache Tez > Issue Type: Bug > Reporter: Saikat > Attachments: OOM_1.png, OOM_2.png, OOM_3.png, TEZ-2850.1.patch, > TEZ-2850.2.patch, TEZ-2850.3.patch, TEZ-2850_test.patch > > -- This message was sent by Atlassian JIRA (v6.3.4#6332)
