--------------------------

             Summary: Using Drill Hive connection to query an Hbase table
                 Key: DRILL-6033
                 URL: https://issues.apache.org/jira/browse/DRILL-6033
             Project: Apache Drill
          Issue Type: Bug
    Affects Versions: 1.11.0
         Environment: 3 instances of Cloudera 5.10v , each one have a drillbit installed.
Each machine has 24 vCPU.
            Reporter: Dor


Using Drill hive connection to query Hbase table.
+*Following query *+
select * from hive.mytable where key >= '0001:10:2017:0410:0000000000003157781'
and key < '0001:10:2017:0410:0000000000003157782';

+*What happened*+
Failed with an error after timeout.
It seems that the word 'key' didn't push down to hive from drill.

+*What we also tried*+
Same query in Drill over hbase takes less than a sec,
In hue hive it takes few seconds

+*Debug trail*+
When you look in the sql profile of drill (using the web), you see a 
table full scan for millions of records, while actually it was supposed to return
9 rows.

Does Drill on top of hive is using the key to access only the relevant 
region of the table?
