Allen Wittenauer resolved MAPREDUCE-257. ---------------------------------------- Resolution: Fixed "prevent a node from swapping" -> "don't exhaust memory" -> "memory limits" -> "fixed" Closing. > Preventing node from swapping > ----------------------------- > > Key: MAPREDUCE-257 > URL: https://issues.apache.org/jira/browse/MAPREDUCE-257 > Project: Hadoop Map/Reduce > Issue Type: Improvement > Reporter: Hong Tang > > When a node swaps, it slows everything: maps running on that node, reducers > fetching output from the node, and DFS clients reading from the DN. We should > just treat it the same way as if OS exhausts memory and kill some tasks to > free up memory. -- This message was sent by Atlassian JIRA (v6.2#6252)
