I am running Hadoop 2.0 with CDH4 and built elephant-bird library with Oracle Java 1.6 r31
My Pig Script:
register elephant-bird-2.2.3.jar
log = load 'loggy.log.lzo' using com.twitter.elephantbird.pig.store.LzoPigStorage(' ');
limited = limit log 100;
dump limited;
Result:

This is caused by an incompatibility between the Hadoop version expected by the elephant-bird library and the one that is installed (this bug report describes a similar problem). The latest version of elephant-bird contains Hadoop API wrappers that solve the issue.
Try the latest version of the elephant-bird library - you need three jars - and register them in pig:
register 'elephant-bird-core-4.1.jar';
register 'elephant-bird-pig-4.1.jar';
register 'elephant-bird-hadoop-compat-4.1.jar';
That solved the problem for me.

I am trying to process multicharacter delmiter in hive.
I already created a table with the same successfully
create external table showtmp3(doc_name STRING,doc_content STRING) row format SERDE 'org.apache.hadoop.hive.serde2.MultiDelimitSerDe' WITH SERDEPROPERTIES ('field.delim'='#a#') location '/unmesha/OUT';
Then I need to issue a query as below.
INSERT OVERWRITE DIRECTORY '/unmesha/OUT_tmpShowData' SELECT * showtmp3 limit 10;
But it is giving me the error below

Should I download any jar and put in some location?
Please suggest
This is probably what you are looking for: http://grepcode.com/file/repo1.maven.org/maven2/org.apache.hive/hive-contrib/0.14.0/org/apache/hadoop/hive/contrib/serde2/MultiDelimitSerDe.java
You can download the original jar from Maven repo: https://mvnrepository.com/artifact/org.apache.hive/hive-contrib/0.14.0
Download this jar file and place it into you hive /lib folders of all nodes of your cluster. This should resolve the issue
you have to add hive-contrib.jar file to the hive. Run the below command in hive shell.
add JAR /opt/cloudera/parcels/CDH <version> /jars/hive-contrib.jar
(or)
add jar /usr/lib/hive/lib/hive-contrib-<version>.jar;

I am running Hadoop 2.0, Pig 0.11, and elephant-bird 2.2.3
I don't use elephant-bird, so I'm not entirely sure that this is the problem.
But looking at their build for v2.2.3, it was compiled against hadoop-0.20.2 and pig-0.9.2. I've seen problems with UDFs in Pig when running on a newer version than what the UDF was compiled against.
Are you able to upgrade elephant-bird to a newer version or recompile against the correct libraries?
I am using CDH4 in a pseudo-distributed mode and I have some trouble working with HBase and Pig together (but both work fine alone).
I am following step by step this nice tutorial:
http://blog.whitepages.com/2011/10/27/hbase-storage-and-pig/
So my Pig-script looks like this
register /usr/lib/zookeeper/zookeeper-3.4.3-cdh4.1.2.jar
register /usr/lib/hbase/hbase-0.92.1-cdh4.1.2-security.jar
register /usr/lib/hbase/lib/guava-11.0.2.jar
raw_data = LOAD 'input.csv' USING PigStorage( ',' ) AS (
listing_id: chararray,
fname: chararray,
lname: chararray );
STORE raw_data INTO 'hbase://sample_names' USING org.apache.pig.backend.hadoop.hbase.HBaseStorage ('info:fname info:lname');
But upon entering following command
pig -x local hbase_sample.pig
I get following error message
ERROR org.apache.pig.tools.grunt.Grunt - ERROR 2998: Unhandled internal error. org/apache/hadoop/hbase/filter/Filter
Main reason I found online would be the classpaths, so here's a list of the current configuration, maybe you find some nonsense in my configuration:
export HADOOP_HOME=/usr/lib/hadoop
export HADOOP_MAPRED_HOME=/usr/lib/hadoop-mapreduce
export HADOOP_CONF_DIR=/etc/hadoop/conf
export HBASE_HOME=/usr/lib/hbase
export HBASE_CONF_DIR=/etc/hbase/conf
export PIG_HOME=/usr/lib/pig
export PIG_CONF_DIR=/etc/pig/conf
export PATH="$HADOOP_HOME/bin:$HBASE_HOME/bin:$HADOOP_MAPRED_HOME/bin:$PIG_HOME/bin:$PATH"
export HADOOP_CLASSPATH="$HBASE_HOME/bin"
export PIG_CLASSPATH="$HBASE_HOME/bin:$PIG_HOME/bin"

Your PIG_CLASSPATH is wrong, it should look like the following:
export PIG_CLASSPATH=”`hbase classpath`:$PIG_CLASSPATH”
This will add your missing hbase-related jars to your classpath for Pig.
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
