Konstantin Shvachko commented on HADOOP-5670:
---------------------------------------------
Centralized configuration facility adds one more single point of failure. If
LDAP server fails - everything fails.
I am not arguing against centralized configurators in general. Just pointing
out possible issues.
Configuration may be just the first step. Then we may want to build centralize
hadoop distribution repositories from which cluster nodes can pick required
jars, etc.
> Hadoop configurations should be read from a distributed system
