[jira] [Created] (HADOOP-11137) put up guard rails around pid and log file handling

Allen Wittenauer created HADOOP-11137:
-----------------------------------------

             Summary: put up guard rails around pid and log file handling
                 Key: HADOOP-11137
                 URL: https://issues.apache.org/jira/browse/HADOOP-11137
             Project: Hadoop Common
          Issue Type: Improvement
          Components: scripts
            Reporter: Allen Wittenauer


We should do a better job of protecting against symlink attacks in the pid and log file handling code:

a) Change the default location to have a user or id.str component
b) Check to make sure a pid file is actually a pid file (single line, nothing but numbers)

... maybe other stuff?
