These 3 options may work for you.
1. Write a mapreduce job manually and use hbase bulkload api (this should work fast but need little bit time to write code).
2. Write a pig script and use pig native Hbasestorage to load your data from hdfs to hbase.
3. Create a hive external table pointing to pig output directory and then create another hive table that should point to hbase table, once you make these tables then you can directly use insert into hive-hbase-table select * from hive-external table( but make sure your both table structure is same).
