TaskMemoryMonitorThread might shoot down tasks even if their processes
momentarily exceed the requested memory
--------------------------------------------------------------------------------------------------------------
Key: HADOOP-5883
URL: https://issues.apache.org/jira/browse/HADOOP-5883
Project: Hadoop Core
Issue Type: Bug
Components: mapred
Reporter: Hemanth Yamijala
Currently the TaskMemoryMonitorThread kills tasks as soon as it detects they
are consuming more memory than the max value specified. There are valid cases
(see HADOOP-5059) where if a program is executed from the task, it might
momentarily occupy twice the amount of memory for a short time. Ideally the
monitoring thread should handle this case.
