INLINE COMMENTS
src/main/java/org/apache/hadoop/hbase/util/CompoundConfiguration.java:160 For
Configuration, the above shouldn't happen.
Disregard.
src/main/java/org/apache/hadoop/hbase/util/CompoundConfiguration.java:369 We
may need this method later.
src/main/ruby/hbase/admin.rb:174 TRUNK version handles htd.setOwnerString()
as well.
src/main/ruby/hbase/admin.rb:177 The error message doesn't seem to match
condition.
src/main/ruby/hbase/admin.rb:346 A check similar to the one on line 188 is
desirable here.

> Dynamic Schema Configurations
> -----------------------------

> Key: HBASE-5335
> URL: https://issues.apache.org/jira/browse/HBASE-5335
> Project: HBase
> Issue Type: New Feature

> Currently, the ability for a core developer to add per-table & per-CF
> configuration settings is very heavyweight. You need to add a reserved
> keyword all the way up the stack & you have to support this variable
> long-term if you're going to expose it explicitly to the user. This has
> ended up with using Configuration.get() a lot because it is lightweight and
> you can tweak settings while you're trying to understand system behavior
> [since there are many config params that may never need to be tuned]. We
> need to add the ability to put & read arbitrary KV settings in the HBase
> schema. Combined with online schema change, this will allow us to safely
> iterate on configuration settings.
