Subject [jira] [Commented] (HADOOP-8332) make default container-executor.conf.dir be a path relative to the container-executor binary
Date Mon, 30 Apr 2012 16:31:49 GMT

    [ https://issues.apache.org/jira/browse/HADOOP-8332?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13265012#comment-13265012
] 

Robert Joseph Evans commented on HADOOP-8332:
---------------------------------------------

I would be a bit nervous about this from a security perspective.  It should not be that big
of a deal because the container executor validates that the conf file is owned by the correct
user, but I have not looked at it that exhaustively.

> Currently, container-executor binary has an absolute pathname of its configuration file
baked in. This prevents an easy relocation of the configuration files when dealing with multiple
Hadoop installs on the same node. It would be nice to at least allow for a relative path resolution
starting from the location of the container-executor binary itself. Something like
> {noformat}
> ../etc/hadoop/
> {noformat}
> Thoughts?
