------------------------------------
# Whether hadoop1 or hadoop2, {{HADOOP_CORE_JAR}} is not zero-length, so the
following doesn't work-
{code}
+HADOOP_CORE_JAR=`echo ${HADOOP_HOME}/hadoop-core*.jar`
+
+if [ -z "$HADOOP_CORE_JAR" ]; then
+ HADOOP_VERSION=2
+else
+ HADOOP_VERSION=1

HADOOP_CORE_JAR=/Users/cheolsoop/workspace/hadoop-1.0.3/hadoop-core-1.0.3.jar
{code}
{code:title=hadoop2}
HADOOP_CORE_JAR='/Users/cheolsoop/workspace/hadoop-2.3.0/hadoop-core*.jar'

# jar-all-h12 shouldn't depend on {{jar}} and {{jar-withouthadoop}}-
{code}
+ <target name="jar-all-h12" depends="jar,jar-withouthadoop"
{code}
# Won't this break BigTop for the same reason as PIG-3905 because ivy will
resolve both hadoop1 and hadoop2 dependencies no matter what the value of
{{hadoopversion}} is?

> Currently Pig distribution only bundle pig.jar for Hadoop 1. For Hadoop 2
> users they need to compile again using -Dhadoopversion=23 flag. That is a
> quite confusing process. We need to make Pig work with Hadoop 2 out of box. I
> am thinking two approaches:
> 1. Bundle both pig-h1.jar and pig-h2.jar in distribution, and bin/pig will
> chose the right pig.jar to run
> 2. Make two Pig distributions for Hadoop 1 and Hadoop
> Any opinion?
