There seem to be the following primary config locations:
How does mapr sync configuration system changes? Do I need to manually sync all changes to these files across nodes or does mapr do some level of syncing on some/all of these? |

/opt/mapr/conf/warden.conf is node dependent and I doubt you need to change anything there manually. Currently we do not have mechanism to centrally modify Hadoop and Hbase configs. This node-by-node management is inherited from Hadoop, of course. We have fewer important variables in these conf files, but they are still node specific to some degree.

@TedDunning does this also account for uniform clusters?

Yes. Uniform clusters are only uniform because all nodes have the same values for node-specific configuration variables.

An update: with MapR 2.0 onwards, the config files can be centrally managed. See http://mapr.com/doc/display/MapR/Central+Configuration |
