[jira] Commented: (MAPREDUCE-220) Collecting cpu and memory usage
for MapReduce tasks
[ https://issues.apache.org/jira/browse/MAPREDUCE-220?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12894821#action_12894821 ]
Philip Zeyliger commented on MAPREDUCE-220:
-------------------------------------------
Scott,
Quick question: have you tried this patch with JVM re-use enabled? On my quick-reading, this patch doesn't handle that case; I don't know if it's a real problem or not.
Cheers,
