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
