Sandy Ryza updated MAPREDUCE-4970:
----------------------------------
Description: After HADOOP-8552, MR child tasks will attempt to create
security audit log files with their user names. On an insecure cluster, this
has no effect, but on a secure cluster, log4j will try to create log files for
tasks with names like SecurityAuth-joeuser.log. (was: After HADOOP-8552, MR
child tasks will attempt to create security audit log files with their user
names. On an insecure cluster, this has no effect, but on a secure cluster,
empty log files will be created for tasks with names like
SecurityAuth-joeuser.log.
I haven't verified whether this occurs in MR2 yet.)
