David Medinets commented on PIG-3880:
-------------------------------------

Good point. Perhaps my version of hadoop is too old?

Hadoop 0.20.203.0
Subversion

>             Project: Pig
>          Issue Type: Bug
>          Components: grunt
>    Affects Versions: 0.13.0
>            Reporter: David Medinets
>
> I pulled trunk from subversion using the following commands:
> mkdir pig
> cd pig
> svn co http://svn.apache.org/repos/asf/pig/trunk
> cd trunk
> ant
> export PATH=$PATH:$HOME/pig/trunk/bin
> export ACCUMULO_HOME=/opt/accumulo
> export HADOOP_HOME=/opt/hadoop
> export PIG_HOME=$HOME/pig/trunk
> export PIG_CLASSPATH="$HOME/pig/trunk/build/ivy/lib/Pig/*"
> export PIG_CLASSPATH="$ACCUMULO_HOME/lib/*:$PIG_CLASSPATH"
> cd ~
> pig
> Then I ran into this error:
> java.lang.NoClassDefFoundError: 
> org/apache/commons/io/input/ClassLoaderObjectInputStream
>       at org.apache.pig.Main.run(Main.java:399)
> When I change PIG_JAR to use the fat jar, I was able to run the pig command 
> without getting the exception.
