Hi Devs/Users;

 

I read the document about HBaseIntegration in hive , and I did a test for
this .

 

the same data stored in hdfs and hbase , I create two external tables and
use the same hiveQL to query ;

 

The result is that querying from hdfs external table costs about 20 mins ,
querying from hbase external table costs greater than 3 hours .

 

Can someone tell me why it happens , is it possible optimized ?
