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.
