jdbc를 통해 하이브에 연결할 수 없습니다.

내 프로그램을 실행하기 위해 gradle을 사용합니다. 샘플 코드는 https://github.com/onefoursix/Cloudera-Impala-JDBC-Example 을 참조 합니다.

그리고 실패없이 저장소에서 예제를 실행할 수 있습니다.

// Apply the java plugin to add support for Java
apply plugin: 'java'
apply plugin: 'application'

mainClassName = "com.my.impala.fetcher.Fetcher"
// In this section you declare where to find the dependencies of your project
repositories {
    // Use 'jcenter' for resolving your dependencies.
    // You can declare any Maven/Ivy/file repository here.
    mavenCentral()
    maven {
        url "https://repository.cloudera.com/artifactory/cloudera-repos/"
    }
}

run {
     if (project.hasProperty("params")) {
         args params
         // args Eval.me(params)
     }
}

test {
        testLogging {
            events "passed", "skipped", "failed", "standardOut", "standardError"
    }
}


// In this section you declare the dependencies for your production and test code
dependencies {
    // The production code uses the SLF4J logging API at compile time
    compile 'org.slf4j:slf4j-api:1.7.7'
    compile 'org.apache.hadoop:hadoop-client:2.6.0-cdh5.4.4.1'
    compile 'org.json:json:20140107'
    compile 'org.apache.hive:hive-jdbc:1.1.0'
}

샘플 코드는 다음과 같습니다.

Connection con = null;
ResultSet rs = null;
try {
    Class.forName(JDBC_DRIVER_NAME);
    con = DriverManager.getConnection(CONNECTION_HOST);
    Statement stmt = con.createStatement();
    rs = stmt.executeQuery(sqlStatement);
} catch (SQLException e) {
    e.printStackTrace();
    System.exit(-1);
} catch (Exception e) {
    e.printStackTrace();
    System.exit(-1);
} finally {
    try {
        con.close();
    } catch (Exception e) {
        e.printStackTrace();
        System.exit(-1);
    }
}

rs.next();

경우 rs.next다음과 같은 예외가 발생합니다

내가 놓친 부분이 확실하지 않습니다.

감사합니다.
