src/test/java/org/apache/hadoop/hbase/client/TestFromClientSide.java:4246 we
need to chop this file into multiple pieces for parallelization, separate from
this JIRA, correct? testFromClientSide seems to be the correct spot since it's
an HBase java client integration test.
src/test/java/org/apache/hadoop/hbase/client/TestFromClientSide.java:4326

> 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.
