             Summary: Issues when using JAVA code thourgh Drill JDBC driver
                 Key: DRILL-1773
                 URL: https://issues.apache.org/jira/browse/DRILL-1773
             Project: Apache Drill
          Issue Type: Bug
          Components: Client - JDBC
    Affects Versions: 0.6.0, 0.7.0
         Environment: Tested on 0.6R3
            Reporter: Hao Zhu
         Attachments: DrillJdbcExample.java

When executing attached simple JAVA code through Drill JDBC driver(0..6 R3), the query got executed and returned the correct result, however there are 2 issues:
1. It keeps printing DEBUG information.
Is it default behavior or is there any way to disable DEBUG?
eg:
{code}
13:30:44.702 [Client-1] DEBUG i.n.u.i.JavassistTypeParameterMatcherGenerator - Generated: io.netty.util.internal.__matchers__.io.netty.buffer.ByteBufMatcher
13:30:44.706 [Client-1] DEBUG i.n.u.i.JavassistTypeParameterMatcherGenerator - Generated: io.netty.util.internal.__matchers__.org.apache.drill.exec.rpc.OutboundRpcMessageMatcher
13:30:44.708 [Client-1] DEBUG i.n.u.i.JavassistTypeParameterMatcherGenerator - Generated: io.netty.util.internal.__matchers__.org.apache.drill.exec.rpc.InboundRpcMessageMatcher
13:30:44.717 [Client-1] DEBUG io.netty.util.Recycler - -Dio.netty.recycler.maxCapacity.default: 262144
{code}

2. After the query finished, it seems not close the connection and did not return to shell prompt. 
I have to manually issue "ctrl-C" to stop it.

{code}
