Testing Apache Kudu Applications on the JVM

+

Posted 19 Mar 2019 by Grant Henke & Mike Percy

+
+
+

Note: This is a cross-post from the Cloudera Engineering Blog +Testing Apache Kudu Applications on the JVM

+ +

Although the Kudu server is written in C++ for performance and efficiency, developers can write +client applications in C++, Java, or Python. To make it easier for Java developers to create +reliable client applications, we’ve added new utilities in Kudu 1.9.0 that allow you to write tests +using a Kudu cluster without needing to build Kudu yourself, without any knowledge of C++, +and without any complicated coordination around starting and stopping Kudu clusters for each test. +This post describes how the new testing utilities work and how you can use them in your application +tests.

+ + + +

User Guide

+ +

Note: It is possible this blog post could become outdated – for the latest documentation on using +the JVM testing utilities see the +Kudu documentation.

+ +

Requirements

+ +

In order to use the new testing utilities, the following requirements must be met:

+ +
    +
  • OS +
      +
    • macOS El Capitan (10.11) or later
      • +
    • CentOS 6.6+, Ubuntu 14.04+, or another recent distribution of Linux + supported by Kudu
      • +
    +
    • +
  • JVM +
      +
    • Java 8+
      • +
    • Note: Java 7+ is deprecated, but still supported
      • +
    +
    • +
  • Build Tool +
      +
    • Maven 3.1 or later, required to support the +os-maven-plugin
      • +
    • Gradle 2.1 or later, to support the +osdetector-gradle-plugin
      • +
    • Any other build tool that can download the correct jar from Maven
      • +
    +
    • +
+ +

Build Configuration

+ +

In order to use the Kudu testing utilities, add two dependencies to your classpath:

+ +
    +
  • The kudu-test-utils dependency
    • +
  • The kudu-binary dependency
    • +
+ +

The kudu-test-utils dependency has useful utilities for testing applications that use Kudu. +Primarily, it provides the +KuduTestHarness class +to manage the lifecycle of a Kudu cluster for each test. The KuduTestHarness is a +JUnit TestRule +that not only starts and stops a Kudu cluster for each test, but also has methods to manage the +cluster and get pre-configured KuduClient instances for use while testing.

+ +

The kudu-binary dependency contains the native Kudu (server and command-line tool) binaries for +the specified operating system. In order to download the right artifact for the running operating +system it is easiest to use a plugin, such as the +os-maven-plugin or +osdetector-gradle-plugin, to detect the +current runtime environment. The KuduTestHarness will automatically find and use the kudu-binary +jar on the classpath.

+ +

WARNING: The kudu-binary module should only be used to run Kudu for integration testing purposes. +It should never be used to run an actual Kudu service, in production or development, because the +kudu-binary module includes native security-related dependencies that have been copied from the +build system and will not be patched when the operating system on the runtime host is patched.

+ +

Maven Configuration

+ +

If you are using Maven to build your project, add the following entries to your project’s +pom.xml file:

+ +
<build>
+  <extensions>
+    <!-- Used to find the right kudu-binary artifact with the Maven
+         property ${os.detected.classifier} -->
+    <extension>
+      <groupId>kr.motd.maven</groupId>
+      <artifactId>os-maven-plugin</artifactId>
+      <version>1.6.2</version>
+    </extension>
+  </extensions>
+</build>
+
+<dependencies>
+  <dependency>
+    <groupId>org.apache.kudu</groupId>
+    <artifactId>kudu-test-utils</artifactId>
+    <version>1.9.0</version>
+    <scope>test</scope>
+  </dependency>
+  <dependency>
+    <groupId>org.apache.kudu</groupId>
+    <artifactId>kudu-binary</artifactId>
+    <version>1.9.0</version>
+    <classifier>${os.detected.classifier}</classifier>
+    <scope>test</scope>
+  </dependency>
+</dependencies>
+ +

Gradle Configuration

+ +

If you are using Gradle to build your project, add the following entries to your project’s +build.gradle file:

+ +
plugins {
+  // Used to find the right kudu-binary artifact with the Gradle
+  // property ${osdetector.classifier}
+  id "com.google.osdetector" version "1.6.2"
+}
+
+dependencies {
+   testCompile "org.apache.kudu:kudu-test-utils:1.9.0"
+   testCompile "org.apache.kudu:kudu-binary:1.9.0:${osdetector.classifier}"
+}
+ +

Test Setup

+ +

Once your project is configured correctly, you can start writing tests using the kudu-test-utils +and kudu-binary artifacts. One line of code will ensure that each test automatically starts and +stops a real Kudu cluster and that cluster logging is output through slf4j:

+ +
@Rule public KuduTestHarness harness = new KuduTestHarness();
+ +

The KuduTestHarness +has methods to get pre-configured clients, start and stop servers, and more. Below is an example +test to showcase some of the capabilities:

+ +
import org.apache.kudu.*;
+import org.apache.kudu.client.*;
+import org.apache.kudu.test.KuduTestHarness;
+import org.junit.*;
+
+import java.util.Arrays;
+import java.util.Collections;
+
+public class MyKuduTest {
+
+    @Rule
+    public KuduTestHarness harness = new KuduTestHarness();
+
+    @Test
+    public void test() throws Exception {
+        // Get a KuduClient configured to talk to the running mini cluster.
+        KuduClient client = harness.getClient();
+
+        // Some of the other most common KuduTestHarness methods include:
+        AsyncKuduClient asyncClient = harness.getAsyncClient();
+        String masterAddresses= harness.getMasterAddressesAsString();
+        List<HostAndPort> masterServers = harness.getMasterServers();
+        List<HostAndPort> tabletServers = harness.getTabletServers();
+        harness.killLeaderMasterServer();
+        harness.killAllMasterServers();
+        harness.startAllMasterServers();
+        harness.killAllTabletServers();
+        harness.startAllTabletServers();
+
+        // Create a new Kudu table.
+        String tableName = "myTable";
+        Schema schema = new Schema(Arrays.asList(
+            new ColumnSchema.ColumnSchemaBuilder("key", Type.INT32).key(true).build(),
+            new ColumnSchema.ColumnSchemaBuilder("value", Type.STRING).key(true).build()
+        ));
+        CreateTableOptions opts = new CreateTableOptions()
+            .setRangePartitionColumns(Collections.singletonList("key"));
+        client.createTable(tableName, schema, opts);
+        KuduTable table = client.openTable(tableName);
+
+        // Write a few rows to the table
+        KuduSession session = client.newSession();
+        for(int i = 0; i < 10; i++) {
+            Insert insert = table.newInsert();
+            PartialRow row = insert.getRow();
+            row.addInt("key", i);
+            row.addString("value", String.valueOf(i));
+            session.apply(insert);
+        }
+        session.close();
+
+        // ... Continue the test. Read and validate the rows, alter the table, etc.
+    }
+}
+ +

For a complete example of a project using the KuduTestHarness, see the +java-example project in +the Kudu source code repository. The Kudu project itself uses the KuduTestHarness for all of its +own integration tests. For more complex examples, you can explore the various +Kudu integration +tests in the Kudu source code repository.

+ +

Feedback

+ +

Kudu 1.9.0 is the first release to have these testing utilities available. Although these utilities +simplify testing of Kudu applications, there is always room for improvement. +Please report any issues, ideas, or feedback to the Kudu user mailing list, Jira, or Slack channel +and we will try to incorporate your feedback quickly. See the +Kudu community page for details.

+ +

Thank You

+ +

We would like to give a special thank you to everyone who helped contribute to the kudu-test-utils +and kudu-binary artifacts. We would especially like to thank +Brian McDevitt at phData +and +Tim Robertson at GBIF who helped us +tremendously.

This summer I got the opportunity to intern with the Apache Kudu team at Cloudera. -My project was to optimize the Kudu scan path by implementing a technique called -index skip scan (a.k.a. scan-to-seek, see section 4.1 in [1]). I wanted to share -my experience and the progress we’ve made so far on the approach.
