Building HBase 1.3.1 with JDK 8

HBase is a opensource NoSQL store built on top of Hadoop HDFS filesystem. Read more about it here

Building HBase 1.3.1 with JDK 8 will bring out some new problems (Well there are some other issues as well). This blog post is to help people who are walking on the same way as I am.

Assumptions

1. You have installed JDK 8

2. HBase uses maven for builds, you should have installed maven.

3. The sources are already downloaded and are present in /home/xyz/hbase

mvn install won't work?

No, you will hit some compilation issues and some shell script failures.

Compilation error

[ERROR] Failed to execute goal org.codehaus.mojo:findbugs-maven-plugin:3.0.0:findbugs (default) on project hbase: Unable to parse configuration of mojo org.codehaus.mojo:findbugs-maven-plugin:3.0.0:findbugs for parameter pluginArtifacts: Cannot assign configuration entry 'pluginArtifacts' with value '${plugin.artifacts}' of type java.util.Collections.UnmodifiableRandomAccessList to property of type java.util.ArrayList -> [Help 1]

Shell script failure

[ERROR] Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:exec (concat-NOTICE-files) on project hbase-assembly: Command execution failed.: Process exited with an error: 1 (Exit value: 1) -> [Help 1]
org.apache.maven.lifecycle.LifecycleExecutionException: Failed to execute goal org.codehaus.mojo:exec-maven-plugin:1.4.0:exec (concat-NOTICE-files) on project hbase-assembly: Command execution failed.

Ok how do I solve them?

1. Edit the file /home/xyz/hbase/pom.xml and make the following changes.

     Before

        ...

        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>findbugs-maven-plugin</artifactId>
          <version>3.0.0</version>
          <!--NOTE: Findbugs 3.0.0 requires jdk7-->

        ...

     After

        ...

        <plugin>
          <groupId>org.codehaus.mojo</groupId>
          <artifactId>findbugs-maven-plugin</artifactId>
          <version>3.0.4</version>
          <!--NOTE: Findbugs 3.0.0 requires jdk7-->

        ...

2. Edit the file /home/xyz/hbase/hbase-assembly/pom.xml and make the following changes. New versions of bash seems to not accept the extra line at the end

     Before

        ...

            <argument>bash</argument>

            <argument>-c</argument>

            <argument>cat maven-shared-archive-resources/META-INF/NOTICE \

                `find ${project.build.directory}/dependency -iname NOTICE -or -iname NOTICE.txt` \

            </argument>

        ....

     After

        ...

            <argument>bash</argument>
            <argument>-c</argument>
            <argument>cat maven-shared-archive-resources/META-INF/NOTICE \
                `find ${project.build.directory}/dependency -iname NOTICE -or -iname NOTICE.txt`
            </argument>
        ...
