[jira] [Commented] (MAPREDUCE-4397) Introduce
HADOOP_SECURITY_CONF_DIR for task-controller
[ 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 still.

> 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.
