Support CF-level Storage Policy

Key: HBASE-14061
URL: https://issues.apache.org/jira/browse/HBASE-14061
Project: HBase
Issue Type: Improvement
Components: HFile, regionserver
Environment: hadoop-2.6.0
Reporter: Victor Xu
Assignee: Victor Xu
After reading [HBASE-12848|https://issues.apache.org/jira/browse/HBASE-12848]
and [HBASE-12934|https://issues.apache.org/jira/browse/HBASE-12934], I wrote
a patch to implement cf-level storage policy.
My main purpose is to improve random-read performance for some really hot
data, which usually locates in certain column family of a big table.
Usage:
$ hbase shell
alter 'TABLE_NAME', METADATA = {'hbase.hstore.block.storage.policy' =
'POLICY_NAME'}
alter 'TABLE_NAME', {NAME='CF_NAME', METADATA =
{'hbase.hstore.block.storage.policy' = 'POLICY_NAME'}}
HDFS's setStoragePolicy can only take effect when new hfile is created in a
configured directory, so I had to make sub directories(for each cf) in
region's .tmp directory and set storage policy for them.
Besides, I had to upgrade hadoop version to 2.6.0 because
dfs.getStoragePolicy cannot be easily written in reflection, and I needed
this api to finish my unit test.
