I think I found it: yarn.nodemanager.delete.debug-delay-sec
From: John Lilley [mailto:[email protected]] Sent: Tuesday, September 02, 2014 2:02 PM To: '[email protected]' Subject: YARN userapp cache lifetime: can't find core dump We have a YARN task that is core-dumping, and the JVM error log says: # Core dump written. Default location: /data2/hadoop/yarn/local/usercache/jlilley/appcache/application_1405724043176_2453/container_1405724043176_2453_01_000002/core or core.14801 However when I look at the node, everything below here is empty /data2/hadoop/yarn/local/usercache/jlilley/appcache I seem to recall there is a YARN setting to control the time these files are kept around after application exit, but I can't figure out what it is. Thanks, john
