Yes, for some reason, although I specify local mode, hadoop is coming into
picture.
bash-4.1$ which java/usr/bin/java
bash-4.1$ ls -lrt /usr/bin/javalrwxrwxrwx 1 root root 22 Oct 31 16:17
/usr/bin/java -> /etc/alternatives/java
bash-4.1$ ls -lrt /etc/alternatives/javalrwxrwxrwx 1 root root 46 Oct 31 16:17
/etc/alternatives/java -> /usr/lib/jvm/jre-1.7.0-openjdk.x86_64/bin/java
I tried rest the following the variables:bash-4.1$ export HADOOP_HOME=bash-4.1$
export HADOOP_CONF_DIR=bash-4.1$ pig -x local
local-hcc-cidmrn-richer.pig/users/p529444/software/hadoop-1.0.3/bin/hadoop:

If I don't reset HADOOP_HOME and HADOOP_CONF_DIR variables, I get the following
errors:
