-------------------------------------
Summary: Add a config that allows us to configure region-level
storage policies
Key: HBASE-27129
URL: https://issues.apache.org/jira/browse/HBASE-27129
Project: HBase
Issue Type: New Feature
Reporter: tianhang tang
Assignee: tianhang tang
<property>
<name>hbase.hregion.block.storage.policy</name>
<value>HOT|ALL_SSD|...</value>
</property>
With this config, we can set region-level storage policies.
We have this config about CF storage policy:
{code:java}
<property>
<name>hbase.hstore.block.storage.policy</name>
<value>ALL_SSD</value>
</property>
{code}
But in addition to CF, we also have some other path under region path, such
like .splits,
recovered.edits, .tmp .
So i want to add a region-level config which could cover the whole path, and if
you have any other requirements for the cf directory, you can continue to use
the previous hbase.hstore.block.storage.policy to specify them separately.
