I'm still a big fan of using LDAP to help us solve this problem. Rather
than push configs, read them from an LDAP store. Roughly:
cn=mygrid
.. define common configs
cn=datanode1,cn=mygrid
... datanode properties
hosts: hostname1,hostname2, @netgroup1, ... Lists of hosts/netgroups this
set of properties applies to
cn=datanode2,
... datanode properties
hosts:hostname4, hostname5, @netgroup2 ... 2nd set of hosts
Etc.
Pushing this is part of the problem. If Hadoop was smart enough to read its
configs from a central store such as LDAP, it would make things much much
much easier.
See https://issues.apache.org/jira/browse/HADOOP-5670 for more discussion.
