Current Hive uses only HDFS as the underlayer data store, it can query and analyze files in HDFS via MapReduce.
But in some engineering cases, our data are stored/organised/indexed in HBase or other data stores. This jira-issue will implement hive to use HBase as data store. And except for supporting MapReduce on HBase, we will support direct query on HBase.
This is a brother jira-issue of
HIVE-705 (Let Hive can analyse hbase's tables, https://issues.apache.org/jira/browse/HIVE-705). Because this implementation and use cases have some differences from HIVE-705, this jira-issue is created to avoid confusions. It is possible to combine the two issues in the future.
