Suppress the message "Supplied authorities: …" org.apache.hive.jdbc.Utils#parseURL emits

HiveServer2にJDBC経由で接続する際に、ログの設定によっては"Supplied authorities: ..."のようなメッセージが出力されます。hive-jdbcの依存するライブラリはcommons-logging、Log4J、SLF4Jなど様々なログライブラリを含んでおり非常にややこしいですが、今回はlogback+SLF4Jで統一するとしてタイトルのようなメッセージを抑制するために以下のようにまとめてみました。

1 pom.xml
2 logback.xml
3 実行してみる
4 参考リンク

pom.xml

HiveServer2へJDBC経由で接続するのに必要なライブラリは以下を参考にします。

HiveServer2 Clients - Apache Hive - Apache Software Foundation

上記リンクを参考に以下のように設定してみました。dbutilsは今回のログの件とは関係なくおまけです。

logback.xml

続いてログの設定です。

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
</pattern>
</encoder>
</appender>
<logger name="org.apache" level="WARN" additivity="false">
<appender-ref ref="STDOUT" />
</logger>
<root level="DEBUG">
<appender-ref ref="STDOUT" />
</root>
</configuration>

<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n

</pattern>

</encoder>

</appender>

<appender-ref ref="STDOUT" />

</logger>

<appender-ref ref="STDOUT" />

</root>

</configuration>

実行してみる

最後に実行してみます。

package sample;
import java.sql.Connection;
import java.sql.DriverManager;
import java.util.List;
import org.apache.commons.dbutils.QueryRunner;
import org.apache.commons.dbutils.ResultSetHandler;
import org.apache.commons.dbutils.handlers.ArrayListHandler;
public class HiveJdbcTool {
static final String HIVE_URI = "jdbc:hive2://localhost:10000/default";
static {
try {
Class.forName("org.apache.hive.jdbc.HiveDriver");
} catch (ClassNotFoundException e) {
throw new RuntimeException(e);
}
}
public static void main(String[] args) throws Exception {
try (Connection conn = DriverManager.getConnection(HIVE_URI, "hive", "")) {
QueryRunner runner = new QueryRunner(true);
ResultSetHandler<List<Object[]>> rsh = new ArrayListHandler();
List<Object[]> results = runner.query(conn, "show databases", rsh);
results.stream()
.map(columns -> columns[0])
.forEach(System.out::println);
}
}
}

package sample;

import java.sql.Connection;

import java.sql.DriverManager;

import java.util.List;

import org.apache.commons.dbutils.QueryRunner;

import org.apache.commons.dbutils.ResultSetHandler;

import org.apache.commons.dbutils.handlers.ArrayListHandler;

public class HiveJdbcTool {

static final String HIVE_URI = "jdbc:hive2://localhost:10000/default";

static {

try {

Class.forName("org.apache.hive.jdbc.HiveDriver");

} catch (ClassNotFoundException e) {

throw new RuntimeException(e);

}

public static void main(String[] args) throws Exception {

try (Connection conn = DriverManager.getConnection(HIVE_URI, "hive", "")) {

QueryRunner runner = new QueryRunner(true);

ResultSetHandler<List<Object[]>> rsh = new ArrayListHandler();

List<Object[]> results = runner.query(conn, "show databases", rsh);

results.stream()

.map(columns -> columns[0])

.forEach(System.out::println);

}

結果は以下のようになりました。

ちなみに以下のように設定すると、

<configuration>
<appender name="STDOUT" class="ch.qos.logback.core.ConsoleAppender">
<encoder>
<pattern>%d{HH:mm:ss.SSS} [%thread] %-5level %logger{36} - %msg%n
</pattern>
</encoder>
</appender>
<root level="INFO">
<appender-ref ref="STDOUT" />
</root>
</configuration>
