Prevent memory intensive user tasks from taking down nodes
----------------------------------------------------------
Key: HADOOP-3581
URL: https://issues.apache.org/jira/browse/HADOOP-3581
Project: Hadoop Core
Issue Type: Improvement
Components: mapred
Reporter: Hemanth Yamijala
Sometimes user Map/Reduce applications can get extremely memory intensive,
maybe due to some inadvertent bugs in the user code, or the amount of data
processed. When this happens, the user tasks start to interfere with the proper
execution of other processes on the node, including other Hadoop daemons like
the DataNode and TaskTracker. Thus, the node would become unusable for any
Hadoop tasks. There should be a way to prevent such tasks from bringing down
the node.
