-------------------------------------------
Summary: Programatically prevent symlink attacks on hadoop pid
files
Key: HADOOP-8461
URL: https://issues.apache.org/jira/browse/HADOOP-8461
Project: Hadoop Common
Issue Type: Bug
Affects Versions: 2.0.0-alpha, 1.0.3
Reporter: Robert Joseph Evans
pid files stored in HADOOP_PID_DIR and HADOOP_SECURE_DN_PID_DIR are vulnerable
to symlink attacks when not properly set. We should programatically prevent
symlink attacks on these files even if the directories are set to something
that others can write to.
