Subject [jira] [Commented] (MAPREDUCE-4397) Introduce HADOOP_SECURITY_CONF_DIR for task-controller
Date Thu, 05 Jul 2012 14:03:36 GMT

    [ https://issues.apache.org/jira/browse/MAPREDUCE-4397?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13407125#comment-13407125

Robert Joseph Evans commented on MAPREDUCE-4397:

This is very similar work to what was done in MAPREDUCE-4219. MAPREDUCE-4219 was done for
yarn and not branch-1 so you probably want to look at that first to reconcile the differences
between the two approaches.  Any changes being made to branch-1 in this respect would be nice
to have ported to trunk and branch-2 for the container-executor because they are very similar

> The linux task controller concurrently hard code the directory to look for its config
file at compile time (via the HADOOP_CONF_DIR macro). Adding a new environment variable to
look for task-controller's conf dir (with strict permission checks) would make installation
much more flexible.
