             Summary: Drillbit does not send the last RPC message when "limit" is appended to queries on hbase voter table
                 Key: DRILL-1984
                 URL: https://issues.apache.org/jira/browse/DRILL-1984
             Project: Apache Drill
          Issue Type: Bug
          Components: Execution - RPC
    Affects Versions: 0.7.0
         Environment: Windows/OS X
            Reporter: Alexander Zarei

. When using “limit” in queries on hbase “voter” table, drill server does not return the very last RPC message. The very last RPC message is the one translated by DrillClient to a null record batch to notify the ODBC driver of the completion/failure of a query.

This problem is only with the voter table; I tested other hbase multi-region and non-multi-region tables  and  they worked fine. 

It is only queries such as 

------------------------------------------------------------
SELECT * FROM (select cast(row_key as integer) voter_id, cast(voter.onecf.name as varchar(30)) name, cast(voter.twocf.age as integer) age, cast(voter.twocf.registration as varchar(20)) registration, cast(voter.threecf.contributions as decimal(6,2)) contributions, cast(voter.threecf.voterzone as integer) voterzone,cast(voter.fourcf.create_date as timestamp) create_date from hbase.voter) T LIMIT 0

select cast(row_key as integer) voter_id, cast(voter.onecf.name as varchar(30)) name, cast(voter.twocf.age as integer) age, cast(voter.twocf.registration as varchar(20)) registration, cast(voter.threecf.contributions as decimal(6,2)) contributions, cast(voter.threecf.voterzone as integer) voterzone,cast(voter.fourcf.create_date as timestamp) create_date from hbase.voter limit 5

that fail because the very last RPC message is not sent from the server to the DrillClient and as a result the driver keeps waiting for it.
