I am getting a NullPointerException when trying to start my hadoop job with access to Cassandra. Here comes the stack trace:

I am running hadoop version 1.0.3 and cassandra version 1.1.2.
Any help is highly appreciated as I have no idea where to start.
Thanks alot!
It looks like you haven't set your output parititioner, like this:
ConfigHelper.setOutputPartitioner(conf, "org.apache.cassandra.dht.RandomPartitioner");

What could be the reason for this error? How can I fix it?
From you error I can tell it might be the problem of JAR.
Usually, this error (java.lang.NoSuchFieldError: DEFAULT_MR_AM_ADMIN_USER_ENV) is caused by jar conflicts. You can check your class path to see if there are any version conflicts.
I notice that HDFS delete commands will randomly fail. For example, in a MapReduce job I delete a directory at startup. Occasionally it fails with the error below, but will succeed on the second try.

Is it that i have to include jar or what else can be the issue
Thanks
You need to include the mapred java archive, depending on which MapReduce version you use, MRv1 or MRv2 (=YARN).
FYI: java.lang.NoClassDefFoundError is always about a forgotten/mistyped JAR-file
I am trying to bulk-populate an HBase table quickly from a text file (several GB) by using the bulk loading method described in the Hadoop docs.
I have created an HFile which I now want to push to my HBase table.
When I use this command:
hadoop jar /home/hxcaine/hadoop/lib/hbase.jar completebulkload /user/hxcaine/dbpopulate/output/cf1 my_hbase_table
The job starts and then I get this exception:

However, I can see that the Guava jar is in my classpath and when I check inside the jar I can see ThreadFactoryBuilder.class.
I am using these versions (and stuck with them):
Hadoop 0.20.2-cdh3u3
HBase 0.90.4-cdh3u3
Guava jar: /usr/lib/hadoop-0.20/lib/guava-r09-jarjar.jar
I do have an older Guava jar in my classpath but I don't know where it came from, I don't suppose it should have an effect.
Any ideas?
what happens if you run:
export HADOOP_CLASSPATH=`hbase classpath`
before running the load? From the stack trace, it looks like the jar is needed by one of the actual tasks though I am surprised to see that this actually kicks off an M/R job.
pig 0.10.0 supports ruby UDF. So, i am trying a very simple example. but got the following error. Do you know why?

I had the same problem. You should look to see if you have a jruby.jar installed w pig.
Seems like the jython.jar was there so maybe that's a friendly nudge for people to use python.
I had to explicitly put the jruby.jar in the classpath doing:
java -cp $PIG_HOME/pig-0.11.1.jar:$PIG_HOME/lib/jruby.jar org.apache.pig.Main -x local myscript.pig
