Prasanth Jayachandran commented on HIVE-20649: ---------------------------------------------- ptest is flaky again.. none the failures look related and are random.. another try.. > LLAP aware memory manager for Orc writers > ----------------------------------------- > > Key: HIVE-20649 > URL: https://issues.apache.org/jira/browse/HIVE-20649 > Project: Hive > Issue Type: Bug > Affects Versions: 4.0.0, 3.2.0 > Reporter: Prasanth Jayachandran > Assignee: Prasanth Jayachandran > Priority: Major > Attachments: HIVE-20649.1.patch, HIVE-20649.2.patch, > HIVE-20649.3.patch, HIVE-20649.4.patch, HIVE-20649.5.patch, HIVE-20649.6.patch > > > ORC writer has its own memory manager that assumes memory usage or memory > available based on JVM heap (MemoryMX bean). This works on tez container mode > execution model but not in LLAP where container sizes (and Xmx) are typically > high and there are multiple executors per LLAP daemon. This custom memory > manager should be aware of memory bounds per executor. -- This message was sent by Atlassian JIRA (v7.6.3#76005)
