Hao Zhu created DRILL-1773: ------------------------------ 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} 13:31:11.239 [main-SendThread(xx.xx.xx.xx:5181)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x1497d1d0d040839 after 0ms 13:31:24.573 [main-SendThread(xx.xx.xx.xx:5181)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x1497d1d0d040839 after 1ms 13:31:37.906 [main-SendThread(xx.xx.xx.xx:5181)] DEBUG org.apache.zookeeper.ClientCnxn - Got ping response for sessionid: 0x1497d1d0d040839 after 0ms ^CAdministrators-MacBook-Pro-40:xxx$ {code} ======== The DrillJdbcExample.java is attached.
