Subject [jira] [Commented] (SOLR-6126) MapReduce's GoLive script should support replicas

------------------------------------

Thanks Wolfgang.  Can you comment how that is so?  (how does it work?)

> The GoLive feature of the MapReduce contrib module is pretty cool.  But a comment in
there indicates that it doesn't support replicas.  Every production SolrCloud setup I've seen
has had replicas!
> I wonder what is needed to support this.  For GoLive to work, it assumes a shared file
system (be it HDFS or whatever, like a SAN).  If perhaps the replicas in such a system read
from the very same network disk location, then all we'd need to do is send a commit() to replicas;
right?
