> Issue in using drill JDBC jar in Java code for Hive storage
> -----------------------------------------------------------
>
> Key: DRILL-3644
> URL: https://issues.apache.org/jira/browse/DRILL-3644
> Project: Apache Drill
> Issue Type: Bug
> Affects Versions: 1.0.0, 1.1.0
> Reporter: Devender Yadav
>
> I am using drill in embedded mode. I added plugin configuration for hive:
> {
> "type": "hive",
> "enabled": true,
> "configProps": {
> "hive.metastore.uris": "",
> "javax.jdo.option.ConnectionURL": "jdbc:mysql://localhost:3306/metastore",
> "javax.jdo.option.ConnectionDriverName": "com.mysql.jdbc.Driver",
> "javax.jdo.option.ConnectionUserName": "root",
> "javax.jdo.option.ConnectionPassword": "root",
> "hive.metastore.warehouse.dir": "/user/hive/warehouse",
> "fs.default.name": "file:///",
> "hive.metastore.sasl.enabled": "false"
> }
> }
> Useful portion of my code:
> Connection conn = new Driver().connect("jdbc:drill:zk=local",null);
> Statement stmt = conn.createStatement();
> ResultSet rs = stmt.executeQuery("show databases");
> while (rs.next())
> {
> String SCHEMA_NAME = rs.getString("SCHEMA_NAME");
> System.out.println(SCHEMA_NAME);
> }
> Exception:
> java.sql.SQLException: Failure in starting embedded Drillbit:
