Hi Chris!   Let's try to keep these threads on a single problem. It sounds like the compatibility issue that started this thread has been addressed. Could you mark it resolved?   Your current problem sounds like it's the same one we started working on when ChunkInputFormatTest failed. Could you follow up on that question with a link to the output of running the maven commandline for building? If you use the rich text editor, there's a button for pasting in code that will help make the output more readable.   In regards to the newer release, I've had no issues using it on the Quickstart VM. However, until we figure out the root cause of your problem there's little reason to change the Accumulo version.   -Sean ... View more

Let's step back and confirm that your VM can properly see the necessary Maven repositories.   I'm using a QuickStart VM with CDH 4.4.0 and I have the Accumulo 1.4.3-cdh4.3.0 release installed from tarballs in /usr/lib/accumulo.   If I open up a terminal and navigate to the install directory, I can successfully rebuild everything including the examples.   [cloudera@localhost ~]$ sudo su - accumulo [accumulo@localhost ~]$ cd /usr/lib/accumulo [accumulo@localhost accumulo]$ mvn -Dhadoop.profile=2.0 package <...snip maven downloading dependencies from the internet...> ------------------------------------------------------- T E S T S ------------------------------------------------------- Running org.apache.accumulo.examples.simple.dirlist.CountTest log4j:WARN No appenders could be found for logger (org.apache.hadoop.metrics2.lib.MutableMetricsFactory). log4j:WARN Please initialize the log4j system properly. log4j:WARN See http://logging.apache.org/log4j/1.2/faq.html#noconfig for more info.

Hi Chris!   That definitely sounds like a problem with getting Netbeans to play nicely with Maven's dependency providing.   To avoid the drag of these kinds of tooling issues, I generally recommend people stick with whatever workflow they're used to for Java development.   Is there another IDE you are more familiar with?   -Sean ...

Hi Chris!   This particular problem is caused by attempting to build Accumulo in Hadoop 1 mode against Hadoop 2 (specifically CDH4).   In the initial Cloudera integrated release of the Accumulo 1.4.x line, you still had to specify the Hadoop 2 profile via a Java system property.   Command line maven would look like this: $> mvn -Dhadoop.profile=2.0 package  I presume there is some way to specify this in the build options for netbeans, but I am not familiar with that particular IDE.   Alternatively, you could install our latest release, Accumulo 1.4.4-cdh4.5.0 (available from archive), which defaults to building against the Hadoop 2 profile.   It might also help to know why you're rebuilding the examples. From your other outstanding question, my guess is that you're using it as a starting point to learn about general development? ... View more

In this case, the warning is benign. It's caused by the inclusion of a symlink from a versionless file name to a versioned file name in the CDH4 hadoop client directory. Since they point to the same jar, you can safely ignore them.   You can confirm this by doing a long listing on the directory mentioned in the error message:   [accumulo@localhost accumulo]$ ls -lah /usr/lib/hadoop/client-0.20/slf4j-log4j* lrwxrwxrwx. 1 root root 43 Oct 7 08:33 /usr/lib/hadoop/client-0.20/slf4j-log4j12-1.6.1.jar -> /usr/lib/hadoop/lib/slf4j-log4j12-1.6.1.jar lrwxrwxrwx. 1 root root 43 Oct 7 08:33 /usr/lib/hadoop/client-0.20/slf4j-log4j12.jar -> /usr/lib/hadoop/lib/slf4j-log4j12-1.6.1.jar [accumulo@localhost accumulo]$   You can clear up the warning by modifying your accumulo-site.xml to use a regex in general.classpaths that will only match files with version numbers in the name:   <property> <name>general.classpaths</name> <value> $ACCUMULO_HOME/lib/[^.].$ACCUMULO_VERSION.jar, $ACCUMULO_HOME/lib/[^.].*.jar, $ZOOKEEPER_HOME/zookeeper[^.].*-[0-9].*.jar, $HADOOP_CONF_DIR, $HADOOP_CLIENT_HOME/[^.].*-[0-9].*.jar, $HADOOP_MAPRED_HOME/[^.].*-[0-9].*.jar, $HADOOP_MAPRED_HOME/lib/[^.].*.jar, </value> </property>   Note in particular, the addition of "-[0-9].*" to the regex for matching jars in the hadoop client directory. It may help to view this change in the larger context of configuration files for working with the quickstart VM. ... View more

Hey Chris!   Any luck getting the output of those two commands somewhere I can see it? ... View more

Hi Chris!   It looks like you have some Accumulo jars in your path that don't work with Hadoop 2 (and thus CDH4).   First, to make sure we're on the same page, earlier I walked through the following:   Get the Cloudera QuickStart VM with CDH 4.4.0 Download the Cloudera release for Apache Accumulo 1.4.3-cdh4.3.0 Follow the instructions for installing above via tarball Walk through the example found in docs/README.helloworld I was able to do all of the above succesfully (after adjusting the installation classpath for using a CDH installation done with packages).   Does this matches what you are trying to do?   Presuming it does, let's step through what could be wrong with your install. Can you open a terminal on your quickstart VM and run the following:   $ACCUMULO_HOME/bin/accumulo version $ACCUMULO_HOME/bin/accumulo classpath Please get the output of both of these commands and paste it into a gist/pastebin somewhere. For comparison, here is the output of those commands on my QuickStart VM. ... View more
