Hive with HBase as data store to support MapReduce and direct query
-------------------------------------------------------------------
Key: HIVE-806
URL: https://issues.apache.org/jira/browse/HIVE-806
Project: Hadoop Hive
Issue Type: New Feature
Reporter: Schubert Zhang
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.
