Subject [jira] Commented: (HBASE-1154) Store hbase-site.xml in ZooKeeper

Evgeny Ryabitskiy commented on HBASE-1154:
------------------------------------------

It's looks same but more concrete for one of cases. I am new to jira but IMO it can be a subtask
of HBASE-1109.

> Right now hbase-site.xml is stored in the classpath of every individual machine.  To
update parameters of the cluster, one has to copy files to every cluster machine then restart
the daemons.
> Instead of storing config files in a local disk, store them in Zoo Keeper.  
> Regionservers can then put a watch on the file, and do something appropriate when the
config changes.  Restarting en-masse is probably not the best solution however.
> A similiar change could be done for HDFS/Hadoop for their own hadoop-site.xml file. 
That is a little out of scope :-)
