Edward Capriolo commented on HADOOP-5670:
-----------------------------------------

Jeff the implementation I want to go for was described above:

I suppose if all we wish is to replace basically the -D options passed into hadoop, then I am very openminded to a ldap based scheme as a plugin. I would be very happy if it included some scoping so that configuration could be provided on a intra cluster, inter cluster, host ,user or job level. Guidelines should be provided as how not to disrupt existing ldap users.

And meet this requirement:

I think we don't need to debate hard on ldap versus zookeeper versus etc on this specific issue. I assume that we would have the abstraction here so that folks can try out different systems - ldap, zookeeper etc. and can configure one as per their environment needs.

Also I wanted to add that since the new hadoop security is kerberos. Kerberos is normally backended by LDAP, so a good point of users will have an ldap server at their disposal.

> Rather than distributing the hadoop configuration files to every data node, compute node, etc, Hadoop should be able to read configuration information (dynamically!) from LDAP, ZooKeeper, whatever.
