---------------------------------
@Ted, thanks for pointting out the test error, I made a mistake, I neglected
the largeTest category test. Now, all UT and integration test passes.
@Andrew, the shell syntax is completely compatible with before, it extends the
function by adding a new attribute "CONFIG", while old attributes still works.
@Lars and Andrew,
I have updated the HBase shell context help in the patch:

or a shorter version:
hbase> alter 't1', 'delete' => 'f1'
+
+You can also change the column family config by set attribute CONFIG like this:
+ hbase> alter 'test', NAME=>'f', CONFIG => {'hbase.hstore.compaction.min' =>
'5'}
You can also change table-scope attributes like MAX_FILESIZE
MEMSTORE_FLUSHSIZE, READONLY, and DEFERRED_LOG_FLUSH.

For example, to change the max size of a family to 128MB, do:
hbase> alter 't1', METHOD => 'table_att', MAX_FILESIZE => '134217728'
+
+You can also change the table-scope by set attribute CONFIG like this:
+ hbase> alter 'test', METHOD=>'table_att', CONFIG =>
{'hbase.hstore.compaction.min' => '5'}

Here is the suggested release notes for this patch:

Release notes:
With HBASE-8176("Dynamic Schema Configurations"), we can define table/column
family specific configuration by HColumnDescriptor.setValue() or
HTableDescriptor.setValue().
We can also do this easily in hbase shell, like this:
Change the table-scope by set attribute CONFIG like this:
alter 'test', METHOD => 'table_att', CONFIG => {'hbase.hstore.compaction.min'
=> '5'}
Change the column family config by set attribute CONFIG like this:a
alter 'test', NAME => 'f', CONFIG => {'hbase.hstore.compaction.min' => a'5'}
