John Vines commented on ACCUMULO-683:
-------------------------------------
Perhaps there's a middle ground where we can handle this. I think when we init
we should do a check and alert the user if they have an issue. We can prompt
them to set the replication there, so if they want to keep the 5 and mess with
their HDFS configuration they can. Or they can set their !METADATA replication
to 3 and be done with it.
