How do I troubleshoot the installation of Apache Accumulo on Linux?

I am trying to install open source Accumulo on RHEL 7.x. I have two GB of swap space. I have installed Java 1.8, Hadoop 3, and Zookeeper. I have run the bootstrap_config.sh script for Accumulo 1.9.2.

I ran this (and expected it to work):

/bin/accumulo-1.9.2/bin/accumulo init

But I get this error:

[start.Main] ERROR: Uncaught exception java.util.ServiceConfigurationError: org.apache.accumulo.start.spi.KeywordExecutable: Provider org.apache.accumulo.proxy.Proxy could not be instantiated at java.util.ServiceLoader.fail(ServiceLoader.java:232) at java.util.ServiceLoader.access$100(ServiceLoader.java:185) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:384) at java.util.ServiceLoader$LazyIterator.next(ServiceLoader.java:404) at java.util.ServiceLoader$1.next(ServiceLoader.java:480) at org.apache.accumulo.start.Main.checkDuplicates(Main.java:237) at org.apache.accumulo.start.Main.getExecutables(Main.java:228) at org.apache.accumulo.start.Main.main(Main.java:84) Caused by: java.lang.NoClassDefFoundError: org/apache/commons/configuration/Configuration at java.lang.Class.getDeclaredConstructors0(Native Method) at java.lang.Class.privateGetDeclaredConstructors(Class.java:2671) at java.lang.Class.getConstructor0(Class.java:3075) at java.lang.Class.newInstance(Class.java:412) at java.util.ServiceLoader$LazyIterator.nextService(ServiceLoader.java:380) ... 5 more Caused by: java.lang.ClassNotFoundException: org.apache.commons.configuration.Configuration at java.net.URLClassLoader.findClass(URLClassLoader.java:382) at java.lang.ClassLoader.loadClass(ClassLoader.java:424) at org.apache.accumulo.start.classloader.AccumuloClassLoader$2.loadClass(AccumuloClassLoader.java:294) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) ... 10 more

I used the Accumulo bootstrap_config.sh script to configure Hadoop version 3. How do I get "/bin/accumulo-1.9.2/bin/accumulo init" to work?

Accumulo 1.9.2 expects Hadoop 2 out of the box, but does have a build profile to rebuild a tarball specifically for use with Hadoop 3. You can build Accumulo with the Hadoop 3 profile by downloading the source tarball and doing:

mvn clean package -Dhadoop.profile=3 -DskipTests

If you're not interested in rebuilding from source, it may be possible to simply fix the class path issues by reading the error message, and adjusting your class path accordingly. In this case, it seems you're missing a commons-configuration jar.
