You may want to try by creating UDF/UDTF hive function

Subject: Hive HBase integeration use case
I would like to have HBase as a data storage and use Hive for data warehousing.
The issue with the integration is,
The HBase table is composed of composite keys following the below structure:
HBase ROWKEY: Hash(customer_id)+customer_id+time+event_id
column: usage : value
The structure of Hbase rowkey makes every entry a distinct one.
Is it possible to split the rowkey and map them as columns of the hive table as explained below:
I am trying to create a hive table with the following column structure:
This will enable me aggregate data by grouping the column ( time or event_id)??
Any thoughts on the same??
If there isn't a direct handling by hive HBase integration, can you suggest any other means??
